Any reason why you didn't move the stock Ohlins 10kg front springs to the rear? Rather than buy swift for front and back?

I bought my DFVs from Patrick at Urge a while ago but recently upgraded to 12/10kg (but only bought a set of swift 12kg springs to do so). I also picked up SBG's lowering cups for the rear (to avoid hitting the bump stop like I already have done a couple times with stock DFV setup.. that sucks). I also got the SBG tophats for front and back to reduce wear (thanks to pivoting capability from bearings). Haven't actually set it all up yet but will do so in May or June.

I got the SBG consultation for my new setup and with 12/10kg, SBG lowering cups, and SBG tophats, stock 2002 AP1 sway bars, SBG recommended preload (for my desired lower height): 2mm in front, 12mm in rear.

Appearance only. Wanted the same look front to back plus I know have extra springs for my other S to so something in the future.

It's been slow progress due to work and family demands but I have the car ready for alignment. I adjusted the ride height to 330 mm on all four corners (+\- .3mm) with 2mm and 12mm preload front to back. On my initial install the front ride height was a 12.7mm higher in the front than the rear. So I re-adjusted. It's a tedious thing to get the ride height correct. Off to alignment and test drive with different rebound settings. Eventually in a few weeks the ride height will be adjusted again with a full corner balance.

Finally got the car aligned today. I plan on a corner balance but for right now happy with my track oriented alignment. Detail of my final specs for anyone interested with 12k/10k setup are as follows.

Front
-3.2 degrees camber
0 degrees total toe
6.5 degrees caster
330mm ride height
2mm preload

Rear
-3.0 degrees camber
.48 degrees total toe
330mm ride height
12mm preload


I'm happy with the functional ride height and look forward to fine tuning some more after some aftermarket wheels and tires are in play.

Took the car out for a short test drive after the alignment. It felt planted as I moved from 15 clicks to 10 clicks from full stiff on all four corners. So far I notice a considerable change in ride quality. Would describe it as smooth and compliant as road imperfections are not jarring and the low speed driving is not bumpy as before. Worth the money even if it's tedious work to dial in the specs.

Hope to have a more detailed driving impression listed here soon.

Got the impulse to drive the CR today and test out the suspension again. I love it. It's so smooth with this 12/10k setup at 10 clicks. At high speed it feels so stable. Hard braking from high speed is vastly improved. That was a nice surprise. Took a few turns at speed and the car was very responsive at turn in and the rear tracks nicely with my alignment. Looking forward to dialing it in more with a proper corner balance after I purchase some adjustable rear control arms.

Great thread !

Thanks.

Did some more ride height adjustments on the front end this weekend. After getting it done, I decided to re-do my alignment as I wanted more caster and wanted to dial the rear toe down a bit. Plus the steering wheel wasn't centered which annoys me. Nevertheless, Nate at Firestone is getting a lot of practice doing custom alignments. New setup works well as I drove it around today. The height is functional and not too low for the moment. I wanted to leave room for some more adjustment when I get it corner balanced. I still need to find some adjustable rear end links before the corner balance can happen. I did source some adjustable rear control arms. For right now, I need to find the correct rebound adjustments for street and track application.

Front
-3.2 degrees camber
0 degrees total toe
6.8 degrees caster
330mm ride height
2mm preload

Rear
-3.0 degrees camber
.40 degrees total toe
330mm ride height
12mm preload

I decided to swap out the rear adjusters I purchased originally for ones from SBG. They have a cleaner look and have a more tactile feel when adjusting the rear.
