It seems that the rears were actually past the maximum height just slightly, so that may have played in this.. we moved around the springs and all to make sure they were good, adjusted the height and made sure all was good..put it all back in, tightened and jazz...bam. Took it for a ride down one of our bumpiest's roads and not a single clunk. Just heads up. :D

Oof, over the max height. Glad you fixed it. What length/rate springs are you using in the rear?

7k. Length? Whatever they offer normally as I didn't really customize my order. But yeah we're just at the tip of under max height so it is sitting nice now, no noises, nothing. :D

It was MAYBE 1/4 inch too tall.. one quick adjustment and recheck to make sure it was level and it was done

Yeah, big up to Astral and Greenblurr for all their love and support.. Or just support in this case. (we've taken off the suspension 3 or 4 times to make it all right..*grumble*)

I switched the shorter 7k rear springs for longer 6k springs right away. I found, with the 275 tires I was using at the time, that I didn't have enough adjustment range to keep from rubbing.

The rate change was to solve handling problems I had with the car in competition. If you want to read about it, see the Stance thread in the AutoRnD forum.

I don't remember the exact lengths. I know I have the springs labeled at home. I want to say the springs that shipped with the coilovers were 650mm and the ones I eventually settled on were 700mm.

Wow, really? That's surprising. I'll be honest though, not sure I'd ever go that wide for competition tires. I think 255 is a pretty good fit all around..but then again I'm also basing this off my skill level and stuff I've read. Once I get more seat time in both autocross and track, then maybe I'll switch springs and agree. :D Thanks for the heads up though. BTW more pics of your car?

I don't take a lot of pictures of my car. Look up other ti greys and that's what mine looks like. :P

I'll have different wheels on it this year. I'll put up some new pictures from events once those are on. This year I'll be on 255s, not 275s.

I recommend treading very carefully when you do take your car to an autocross or track. If you find it to be a handful, you'll know what change needs to be made.

Gotcha. I'll keep that in mind. As for dampening..any recommendations? I have 8 all around right now and it feels fine..maybe a bit softer rear though?

I started out at +6 front and rear, as Stance recommended. I finished the season with the rears set to full soft and the fronts to +2. I have little doubt that will change, but probably not drastically unless I start changing spring rates...which I just might do. I am also undecided on the issue of tires, and I'm sure adapting to something new will affect my settings.

Good point. Well what would you recommend for someone like me? The reason I'm asking is because Astral took my car back from the alignment and all and said the car felt like it had a bit oversteer feel to it. Ran a similar alignment before so don't think it's that..but I could be wrong. Maybe +8 front and +6 rear? And whats the benefit of running softer anyways?

I don't know you. Have you autocrossed or been to a track before?

In what situation did your friend determine that the car was oversteering?

I was adjusting for the rear. The car was twitchy and oversteering in nearly every situation. The rear tires were very quickly overwhelmed. I couldn't count on it in sweepers, quick transitions, under braking, etc. I eventually set the rear to full soft, and I kept the front close to it but a little stiffer because the responsiveness seemed to work up there.

Again, this may all change this year on different tires. I consider what I arrived at a good baseline to start from.
