First drive with powertrix coilover

Jhill · 11-14-2016, 08:05 PM

Spoke to Charles and he will look into getting some 10/8 swift setup, I'll have to see if fortune will sell me just the spring seats, I can't use the blue swifts up front as they are a smaller diameter, so I'll need orange 10k up front and blue 8k rear maybe even 11k F 8k R. Also did some more adjustment on the rear as I think there was some confusion on proper shock length vs spring collar adjustment, doing it the way Charles described left the springs loose at extension so I just adjusted the shocks to have the springs just barely engaged. I think this still had too little spring preload and it appears I was hitting the bump stops quiet a bit, so after talking to charles he wasnt really certain as they usually install the spring and then the shock (also they usually set them up much lower) but he also think the shock may have been too long (so not enough shock stoke at ride height), so now I have shortened the shock as short as I can by hand (so as much preload as possible with just hand tension on the body) and made both side =.

No I'll test for the week and see what I think.

So took freeway 87 home today (bumpy *** freeway) and surprisingly I think I am really starting to like these coilovers. Not sure if they had to settle or if after re adjusting the rear shocks heights/spring preloads made all the difference but pretty damn nice. A little bouncy over some stuff so I will slow the rebounds another two clicks but it's starting to grow on me. Good news is I'm not full soft so worst case I drop to a 10/9 setup and I'll still have enough rebound to take out so the softer spring doesn't pack up, so either way the shocks will work for me.

Going over some humps in freeway you can get airborne off your seat once the rear goes over, similar to what happens in a heavy duty truck with the bed unloaded. Over small ripple bumps and bots dots they feel good and maybe even less jarring than oem but I'm not sure I can take the trade off. Nothing against the built quality or anything there, all that looks nice quality.

So a nice product but maybe not the right product for me. I have a track event dec5 so I'll probably keep them until after that unless I get an offer before then and can switch it out in time and then I think I'll consider what I was thinking before and try the rs-r.

lmao, sorry brother but i cant stop laughing at that

Lol, but if you haven't driven the freeways in the LA metropolitan area you can only imagine. It really is not hard to get airborne on some of those highways!

Good that things are getting close to your liking. Charles' help will get you there. I was quite happy on the onset with my 12kg/11kg set up. Going on 3 years now and no issues. It's a personal decision and very pleased with Powetrix w/Swifts after having experienced OEM, H&R's, and Powertrix's factory springs.

We all agree that some CA freeways are a bitch. I vote the entire 405.

Lol yea but at leas so cal freeways were built on solid ground. While 87 is better than it used to be it's still built on marshland (following Guadalupe river) so pretty much not an even stretch the whole way. Now I have the setup at one click towards fast from middle for the front (so 8 clicks out) and rear one click in from half (7 clicks out). Now it finally feels much flatter and more compelled over humps etc while still not packing up over ripples. Now I just need to test full slow to hopefully make sure it can be slowed down enough for smooth track course. I know Charles said he uses them at full soft so that's where I started at but man that seems unreal to me. Usually I always start at middles and tune from there, with the exception of a couple suspension companies that for some strange reason start their usable compression damping at full open so then you start full open compression and middle on rebound (fox).

So I forget who's installing theirs next week but I say start at middles and save yourself the ejection seat lol.

Good news is with the wide range of rebound, not sure about full slow yet but there is absolutely enough range to drop a couple rates if needed which I may actually do and still keep these 12/11 as they are not so bad after all but might do like a winter/summer setup with softer in winter when road are shittier and more slippery requiring more mechanical grip and I won't be tracking in winter anyway so don't need as much rate.

Planning to go with swifts upgraded on these coils. would u guys recommend 12k or 13k fronts? rears are set to 11k.

xxAGAVExx · 01-01-2017, 08:24 AM

I've only had mine on for a few weeks, I have the 13k and don't think they're too harsh on the street, I'd go with those

I too had mine installed a couple of weeks by none other the man himself "Charles", and all I can I say is that they're amazing. As per his recommendation, I set the damping on both at an equal setting so I'm at 7 clicks out from soft. Great product!

Yea the front isn't bad at 12k I just wish I could keep the rear from bucking on rebound after a sharp dip. I now have front a 4 clicks out from firm and rear at 3 clicks out from firm and it helps but then gets a little harsh over rough surface (follows the ground too tight). I think I will end up testing a 10/9 setup, only lowering the front to keep a similar ratio front to rear as the 12/11. Just hope it doesn't completely kill their track usage, still has to be better than stock and a lot of other coilovers aren't running as high a rate so maybe a good compromise.

Why don't you just go full soft and see if that solves the bucking and going airborne issues?

xxAGAVExx · 01-01-2017, 05:15 PM

I'm 10 front 8 rear from soft, seems to feel good on the street, I'll probably bump it up for track

Did you go with 13kg fronts with our California roads?
