SPL rear titanium mid links, springs???
Help post 13!!
If I buy the spl mid links I can no longer use my swift spec-r rear springs or OEM. What do you all suggest that is a good replacement from swift? I see most are 2.5" in diameter but length are all different. When I talked to Fortune Auto about their 510's and I told them what the car was for and they suggested I buy their coilovers with 15k front and 13k rear. The swift spec-r now I believe are 10k front and 10.5k rear but obviously on OEM shocks. I don't have money to do the coilovers now and the mid links if I go OEM coilovers or true coilovers and SPL rear toe arms. I need rear toe adjustment at the moment and it's all I care about. So the cheapest plan is mid links with new rear springs. Should be under $1000. But do I buy the 13k spring now or buy a softer spring until I can get the front coilover to match with it plus a new rear shock that can handle that rate? Also the 13k spring might be bad with the OEM shock plus 10k front and 13k rear might handle like ****. So let's say I go with a 8k, 9k, 10k, rear...do I buy 6" spring, 7", 8"??? The mid link can obviously adjust height so maybe it doesn't matter? But if it didn't, why does swift make a 5,6,7,8,9,10,11" spring in a 65mm ID? |
57 views and no response? No one has OEM style coilovers?

the cheapest option would be to install an aftermarket toe bolt for more adjustment (cutting & enlarging required(

It currently sit at 1/2'' lower 27 1/2 Vs 28'' oem (ground to center wheel arches) and I'm not answering the last question, hehe its a bit obvious. |
Swift makes universal 2.5" ID springs because they're just that, they're universal to span different applications. It's just a spring so multiple cars can use them.
I went with SPC toe bolts to adjust toe because I didn't want to buy new rear springs for my Bilstein coilovers. So I have all of the SPL parts except for the mid link. As far as spring length for the rear, check out this thread: http://www.the370z.com/brakes-suspen...lovers-v3.html ENT-Z used a 2.5" ID 7" length Swift universal spring with his SPL mid links. Don't even know if I answered any of your questions, but personally I would just get the toe bolts and call it a day. Not sure if Fortune Auto coilovers are "true coilovers" in the rear, but if they're OEM-style, then I would just go toe bolts and skip the mid links all together. That's what I did at least. I figure if you got the super high spring rate in the rear expecting to switch out to Fortune Autos later, it'll probably handle like crap until then because your spring rates are going to be all weird. |

I don't want slippage. I want all solid bushings and lockout kits, you name it. :tup: FA coilovers are a OEM type which is why they suggest a 13k rear. A true type like spohn runs is only a 5k. It's like half the weight in a true type. Since ill do FA later I still need the mid links for toe. Plus you eliminate some parts in the rear since you need your OEM link plus the height adjuster sitting in it. Spl is more simple and cool :happydance: |
SPL Mid links are great. The 7" Swift 60mm spring is what I am using with my mid links and my OEM type twin mono flex coil overs. I went with 12K rate (tein mono flex comes with 14K front and rear) but after further research after I bought them I think I would go with 10K if I had to do it over again. My first track session on this new set up is in a few weeks so I will see if I need to swap springs - luckily they aren't crazy expensive!

Well I bought the spl mid links. Bought used springs. I believe they are 10k and 2.5" ID and 6". We shall see when they get here.

Holy geez these are tiny. Swift little weighs 1.88lbs. Swift big weights 8.2lbs.
OEM arm with upper and lower rubber, 1.00, 0.40, and 3.84. Spl arm 6.06, upper metal mount 1.42. Dammit! More rear weight loss. Im already 57/43 ratio :shakes head: |
I'm worried about something if someone can help...
I installed the spl mid links and the 6" swift 10kg springs. The car is at a ride height of 26 3/16th on both sides. I don't remember where the car sat before the install with the swift spec-r's. I know it was 26 something, I think high 26. The spl mid link is about half way to get to that height and where spl said it should be. The issue is if I jack the car up the spring almost falls out of the bucket. If this happened it'd be a total crash or worse! So basically I have zero preload if that's what you call it. I've seen Z's on three wheels before so there is a chance the spring could pop out on a track. Not to mention the loud banging all the time as the spring pops in and out over big holes all the time beating up the upper and lower buckets. What do I do? Buy an adjustable length shock? Almost popping out, only one side jacked up. http://i39.photobucket.com/albums/e1...ps5cf10557.jpg http://i39.photobucket.com/albums/e1...psc75c962d.jpg http://i39.photobucket.com/albums/e1...ps29cbc155.jpg |
you need a 7" spring ... stock is 10" and the midlink changes the geometry height about 3 inches higher than stock ...
