I have Stance GR+Pros coils and they come with 9k-6k springs. So it's what I have on me right now to try out. Currently I've been driving back on 215 to learn limit on my car and the suspension. I'll be going back to either 235 or 245 for my next season of Auto-x
My setup is:
Stance GR+Pro 8k/7k
Whiteline Sway front and rear. Soft setting in the front and Stiffer in the rear.
All SPC arms for the rear.
Some ebay Spherical tension rod in the front with Tein tie rods.
Nismo power brace and f/r ebay struts bar.
Nismo 1.5 LSD
-1.8 camber front, 0.1 toe (stock setting), i think 6.6* caster
-1.4 camber rear, Stock setting toe?
My alignment is not dial in yet... I have a old RLCA that needs to be replace.. =|
I wished I could get my video's of the pass auto-x and from another date so I could show you how my car handles. In this video
YouTube - NorCal UFO Marina Autocross Runs 5/2/10 I couldn't keep my rear in check at all it just wanted to slide. This pass auto-x I adjusted my preload in my rears to add a lil more on the spring helper and it fixed my oversteer problems. Over 2 years ago I use to play with my preload a lot to see how it could effected the suspension but that was before auto-x where I learned how to race more or less.
I like your thought behind all of this work and I'm wanting to follow. Just like you I DD my car everyday and track it. But the roads I DD on BAADD like that haven't been worked on for 25 years now. So I've been thinking how to balance out softness with being able to apply good roll stiffness to that car. I do the same thing the shock better much at the softest setting and it ride alright just get some extra bounds.
That's a interesting about thought about the rear drool I haven't thought about that. I need to change out my bushing.. I still haven't thought about it yet to use poly or Spherical yet. But after reading your setup I may lead toward Spherical now.
I know haven't had a problem with lifting yet. My car has it is look like it's flat through everything but inside you can feel the roll and it isn't bad roll at least to me.
Since my front sway is actually not that much bigger than stock I still feel roll. I don't mind it till it effects my handing. So I want to try out what softer springs and a stiffer setting on sways will do to my car.
Sorry if my English is a messy and I start to ramble a lot think... But I'll let you know what happens when I change my springs out.
Thanks for the input!
