Stance Pro Comp 2 Coilover Review
 

Alright everyone as the title states this is the first review of the Stance Pro Comp 2 Coilovers. I first would like to thank Charles at B2 Auto Designs for the great service and great price in getting me these coilovers. Stance did not make these yet for the 370Z so he had to talk to them and I also wanted the Swift springs option for 13k front, 9k rear. The wait time on these was 7 weeks out of the quoted 6-8 week wait time. They came in literally a week before my first autocross event this past Saturday.

When they did come in the packaging was very good and came with everything even the new nuts for the rear lower bolt and mounting hardware for the external reservoirs. Since these were “true type” coilovers I decided to get the SPL camber and toe arms. I ran out of funds for the front arm’s but it’s the next thing on my list after wider wheels and tires.
The install was a pain because the one northeast winter I put my Z through made all the bolts tough to loosen even with an impact wrench. But I got everything on with a breeze. For the mounting of the external reservoir’s I ran the front through the fender liner to the engine compartment and the rear I used the supplied self tapping screws to mount them to the old not used spring perch. Once got everything on and car lowered on the ground I mounted the front res. to the Stillen intake tubes because the res. hoses aren’t that flexible and it allowed shock travel to not stretch and snap the hose connection.

Once I drove the car home the rear was wayyyyyyyy to low so i maxed out the rear height up. The manual said to set the compression and rebound to the 0 setting then adjust by two clicks from there. I decided to go more soft because I was just commuting to work 5 mins away and did not have an alignment yet. Once I got an alignment after 5 days of little driving the car was more of a beast.

Street Driving: On soft settings 3 comp front/ rear and 3 rebound f/r. the car is very docile and handles great. Going over bridge joints you can really feel the stiff springs. Also I noticed more road noise from what I think the true type setup and all the vibration and energy going to the shock towers. I also drilled a hole in the plastic for the compression adjustments on the rear shocks so that might be why also. When on the freeway and smooth roads you cant tell the difference between stock and the Pro comp 2’s. Bumpy roads is alittle rough but not too bad.

Autocross: Holy Crap! The difference I felt from last year and this year was unbelievable. I started out at the 0 setting all around. My first run I noticed the car was still alittle too soft. So I raised the comp 2 clicks and rear rebound 2 clicks also. The next run I decreased my time by two secs and noticed jacking on the rear on corner exit. So I decreased the rear rebound 2 clicks and still felt more body roll so I also increased the front comp 2 clicks. The next run the car was way too stiff and I was 1 sec slower. So I put it back to my last setting where the felt nice. I am running BFG sport comp 2 tires so that has something to do with it also, plus the first part of the course was slippery with dirt. The second settings I made were the best for my current alignment and tires and I then decreased my time by two more secs. for the next two runs. Whenever I came back into the paddock there were always one of two people saying I was flying and were impressed, (because I was). I was also driving on a new quaife LSD too so that was different than last year as well. The car was neutral and went right where I wanted it to with great breaking and cornering. My alignment was set up to my specs also which is in my journal if you want to look at it. So the final good setting was front comp- 10 reb- 8, rear comp-8 reb- 3.

Final thoughts: For the street if you don’t mind the added road noise or slightly harsher springs than these coilovers are the way to go if you have a dual purpose 370Z. The price was spot on for my budget, (cheaper than KW v3 and what's on the stance website). You get a fully adjustable setup and added external reservoir and you have the ability to adjust gas pressure too! Which im not messing with yet because lack of knowledge. For AutoX or track days/ HPDE these puppies are the way to go. Fully adjustable and DO make you faster. For the weight conscious people the reduced weight by switching to a true type with the swift springs also is a plus. I have had lowering springs and Bilstein shocks in past car and having all the added features of the Stance Pro Comp 2 coilovers they don’t compare. I couldn’t be happier with my purchase. The build quality was great, support for questions was great from stance, and the price was right too. The only downside is the wait, I was anxious the entire time and couldn’t wait to put them on. The main thing they were installed and set up for my first auto x event. No problems at all and I would recommend these to anyone in the future and if you want great service and no problems go to Charles at B2 Auto Designs here on the forum.


Note: I do not have any sponsorships or personal relations with either companies just received good service and want to return the favor.

Have you got any HPDE events on these yet? Do you have to fab up the reservoir backets or are they included in the package you bought. You mentioned maxing out the hieght adjuster in the rear does that get you back to near stock hieght?

good review thanks

just looked at the pic again and brackets are right there lol

That height gets me .5 in from stock but I also don't have it corner balanced. In July I'm doing a track day so once I go I can report back with an update for an hpde.

I got the Stance Supersport + that I'm gonna have put on while I'm out on deployment. I noticed the NWU's so I know you feel me.. lol

Nice! I love my coilovers so far. But good luck out there.

WOW! Thanks! My mechanic works with a supplier that is close with Stance. He's always pushing me towards their coilovers, but I was worried they just weren't up to spec with KW or Fortune Auto. Great review. I may lean toward these now!

Just put 20% down. Can't wait

Phuck Yha. You won't be disappointed. Did you end up getting a longer hose length?

Awesome review and + points for the SF Giants decal!!

Not yet. We just talked about valving and such. He has 2 sets, ones sold and he's a block away from Stance so once I pay the rest he has to pull the bottoms off the them since they're really only made for the 350z, revalve, bigger springs etc and I'll tell him then about the lines.

Nice! I'm going to add that to my list of things to do during my Z's hibernation period this winter.

Thanks, I grew up in San Jose then moved when I joined the navy, I could never drop being a giants fan even if I get crap for it at all the car shows/ meets and autox. These Red Sox fans out here are ruthless.

But back on topic, I've had these on for a few months now and no problems after 2 autox events a month since I got em. I just wish the lines were longer in the rear so I don't have to crawl under the car to adjust compression. But you can always ask to have them longer.

Custom bitch! :tup: not bad for 7/21 fully paid till 8/12 delivery.

18k/12k

DD should be fun.

Congrats Looks good, I guess the guy you know pulled through good as you got yours in less than a month. What spring rate did you end up getting? Mine are just now getting annoying for my wife to drive it more than twice a week :) but I love it.

Yeah 3 weeks wasn't bad. I don't even think they started till 2 weeks ago though. It was good having his shop 18 min from Stance to push them alone.

I posted it, 18k/12k. Lol mine should kill my wife then.

Haha. Good stuff.

Wtf???!!!??!

That goes away after a week. I called them on that, but i freaked out too. It's the valves breaking in.

Its loud as ****!! Well I'm gutted but still. I knew it was internal and the piston shaft moving up and down. When I turn into my garage and go real slow that noise is real slow too like opening a old door in a haunted house. Its embarrassing! :shakes head:

Yha mine was loud too but he only thing I hear back there now is the solid bushings and road noise. Funny thing is when I sent stance a video clip, my gopro w/ external mic couldn't pick it up out side the car (wheel well), it was only heard inside near strut tower. But I spoke with their engineer and it was a normal noise. Where did you mount the reservoirs?

Ok thanks. Scott at Stance and Adam at race consulting couldn't tell me anything. I really hope you're right because it sounds like the shaft is F'd!!!!

Through those holes will also go brake duct cooling lines to use up that space.

This video scared my dog:bowrofl:

Did you notice on the rear lower mount that the mount was to big for the bushing it wraps around? My mount was like 1/8th to big but when I tightened the bolt it closed the gap by bending it inward.

Also, did you notice the same lower mount has one hole WAY to big! One side with the nuts normal but the bolt head side is a 1/8" gap all around.

Tell you the truth I can't remember. I did notice it was hard to get the old bolt out. I had to use a persuader and "mechanical agitation" to get the damn thing to move.

But your locations are more perminate than where I put mine, phuckinlegit. You just movtivated me to refine my res. locations. :tup: looks good.

Hmm mine popped right out. Long as the suspensions unloaded and you pick up on the knuckle.

Well noise is still there. So loud, so annoying. Something wrong in the upper mount area.

Can you guys put up more pics of the rear coil overs installed

Noise is still there. I want to kill myself!

Heard that noise for myself, it would drive me crazy too.

Why would you go progressive with the helper spring?

It's not. The suspension is unloaded. The helper is only like 50lbs. Isn't 100% compressed and unused once loaded.

Idk dude. Mine sounded like that for a week or so. But I don't hear it ,now. Maybe put some more miles on them and soften the settings to work them alittle more. Try Calling them up again on Monday and email them the link to your video.

You were right, it's the valves. But after several hundred miles and a track day they should be "broke in." Stance is sending new 1 ways with helper springs and 12k's, taking mine back, going to fix it, and send them back. So plus 1 on service thus far.

Nice, thats good they arent leaving you high and dry. Everytime i called them i was very satisfied and never angry afterwards. Did they give you a timeline when you would get yours back?

Sending out today, maybe a week turn around.

Did the noise end up completely going away? Would love to hear a follow-up review w/ these

I messaged Synolimit a bit before putting in my order and from my memory, his new set fixed his issues with the old one.

Yes they fixed it. A valve was locked.

So far after 2 years I have not had a problem. My only gripe is when I adjust the compression to full soft the rear shocks click alittle on crappy roads but I only have them soft when my wife drives my Z, (maybe twice a month).

I haven't been to the track or autox in a year so I don't have anymore data on that. But back roads my car is still a monster.

So I'm finally going to return my coilovers to be fixed again. It wasn't a problem at first but now it is since I need more adjustability. The lower mounting perch that stance included is too short. I cannot raise the car up anymore and I'm rubbing even though I have a widebody and my OEM fender is cut out. Because the lower perch is too short I've had to raise my car using the upper spring mount. The rear spring also uses a helper spring which at this point is 100% useless because I've had to tighten the upper mount so much to raise the car up. The helper spring is 100% smashed up which is putting way too much preload on the spring. So I called stance and they are going to take them back and give me a new lower and longer perch mount and inspect and do anything that they need to. This should only be a problem for me and the OP as we were the first to buy these and it was pretty much a custom set up for us. I'm sure by now all their kinks have been worked out.

PS i've only now needed this adjustment since the car is on track and I've been having rubbing issues along with too much understeer and I need all of my help spring to be used.

Are you needing stock height or higher due to setup? I'd read they should be able to adjust to at least within .5" from stock. Or is it an issue with that particular set you got, that it the perch was shorter than it should've been?
