Re: Suspension tuning - dampers, spring rates, etc.

Yep, agreed that bottoming shouldn’t be an issue at that sorta height. Also agreed that it’s time to start looking at other parts and prying on stuff with a bar/screwdriver to see what moves. I’d look over everything… upper and lower ball joints, tie rod ends, compliance bushing, etc. in an effort ...

Re: Suspension tuning - dampers, spring rates, etc.

Appreciate the detail :beer: I’m wondering if it’s a case that you’re bottoming out the suspension travel. Are your Koni’s standard length or shortened? How low is the car? Sorry for the late response. I don't think that's the case either. They are standard length and the collars are as high as the...

Re: Suspension tuning - dampers, spring rates, etc.

Apologies if it’s on an earlier page… but what’s your current suspension setup and wheels/tires? Also, just to clarify, the unsettled feeling is bumps mid-turn or even when going straight? How’s the stability under hard braking (straight line)? Only minor suspension mods: Koni Yellows GC 430/350 Sk...

Re: Suspension tuning - dampers, spring rates, etc.

From what I’ve consumed, it’s generally very hard to correct double wishbone geometry once lowered. If a lowered a small amount (LCAs are level or angled slightly up to the inside, under weight) I believe you’re better off running OEM ball joints. If lowered aggressively (LCAs point down to inside)...

Re: Suspension tuning - dampers, spring rates, etc.

What's the general consensus on extended ball joints/roll center kits? Did some looking into them this afternoon but most threads are 2010 or older and the opinions are divided. A lot of companies made/make them but Honed Developments seems to be the only one that's done "testing" and has...

Re: Tire Information Thread

Local autocross competitors are having success with RT660. Top 5 finishes and they were on RE71R before. I've heard it doesn't fall off as quickly while lapping and also won't heat cycle out as quickly (compared to RE71R) I’m stuck in the past, when I couldn’t get the re71rs I fell back to 615k+ fo...

Re: Brakes 101 (and 102)

If you’re looking for cheap and effective, I’d give these a try: https://www.powerstop.com/product/power-stop-track-day-brake-pads/ Looks like they’re ~$80 from Summit so they’re dirty cheap. I ran these after using up a set of DS2500’s on my AutoX STi (also tried some Hawk stuff). They tended to du...

Re: Tire Information Thread

Lots of good info here for a new owner! I have been looking at the Advan A052 in 205/50R15 for my ITR on the OEM wheels. I will be lapping the car 2x/month once it is finished and I'm thinking these will be a good choice. Anyone with experience with them? Is your suspension setup stock or close to ...

Happy to help. :)

The size constraints limit choices a little but you’ve still got some solid options out there.

Re: Tire Information Thread

I’ve read Sport Comp 2’s, DZ102’s, Ventus V12 EVO2’s (for S2K & CTR), etc. being good tire selections for daily driving. Can anyone else recommend other options for street driving only? For legit DD’er tires or something for the street but still sporty? If you’re looking for street+sporty but s...
