STX setup sharing thread (2023)

[e1_griego]

I have everything from +35 to +42, and I usually run a 3-5mm spacer with everything (with so much camber it's all fine).

I couldn't tell a difference in amount of rubbing between any of them and it smokes a fender liner maybe once a year (~250ish runs) regardless lol.

I see people on here and the other STX setup threads running +42 without spacers. Probably a 40/60 mix on +42/35. If yours and others are rubbing with +35, I don't know how they're getting away +42. Possibly different ride heights. Even then, if it's rubbing on the inner fender, that doesn't really help.

Maybe going with +35 isn't a bad idea then.

First of all it's only 7mm we're talking about so other factors can matter more, but of course it helps.

Second of all whether you rub depends on your 1) ride height 2) alignment 3) springs and shocks 4) level of grip and 5) how bumpy the site is.

If a good driver on an ideal setup is cornering hard and hits a bump mid corner, that's going to take a lot to not rub. Whereas if the site isn't bumpy, it'd be much less likely.

Anyway I run +35mm also with a 5mm spacer in front, with 4.8 camber and 245 yoks. I usually don't rub but sometimes will rub a little where the fender liner goes over the brake line at high grip bumpy sites. The rear I don't have a spacer, and no rubbing no matter what.

I'd just do 35mm on a gen1.

Thanks, I'm edging towards +35 now. I kinda don't love the whole stancey boi look, but I guess with ~4 degrees of camber up front, it won't look bad. I have 3mm spacers on the car right now with ARP studs, so if it needs a bit of 'tuning' to get mine to fit, I have some wiggle room.

I did just pick up some RCE SS-1's today for a bargain. 1500 miles. Can't wait to get this setup for STX-lite. After 4 years in DS, I've had enough.

My other option is getting the +42 and using the 3mm spacers to get around a +39. Problem is, if some people are rubbing on +35... eh, +39 won't be enough.

They sell a version with rubber bushings vs spherical.

I run 255/40 Yoks on my 2017.
-4.3 camber up front. -1.7 camber in rear.

I have a +35mm set of wheels and a +40mm set of wheels.
No spacers.
The +35mm setup I had a very tiny but of rub on the uppermost mounting tab for the rear bumper, shaved a few mm's off and no more rub.
The +40mm setup I get a pretty strong rub at full steering lock on the inside fender liner and 'frame'.

No other rubbing and on our primary lot I've had the car airborne mid corner.

Yep or alternately you can just buy the polyurethane version from verus directly if you pick the poly option here https://www.verus-engineering.com/sh...1#attr=204,100

Good to finally meet a bunch of y'all at Charlotte, even if I was breaking up the Twin party this weekend! Was planning on driving my car, but last minute change of plans while my shocks are off for a refresh. Lead to some confusion at reg where my wife and I somehow ended up registered in my BRZ in STX instead of her RX-8.




My fastest runs for comparison:

[steverife]

Do we know how much toe changes by raising (or lowering) the car by say half an inch?

[strat61caster]

From 27” down to 24” at the rear fender arch each inch of ride height lowered netted me a 0.04” increase in toe in.

So this year I went from -3.6* front camber to -4.7*. I have found that when transitioning in slalom or during sweepers I have developed oversteer. I am assuming do to the increased front camber. Question is what adjustments to make to bring back rear grip? Currently running whiteline 20mm front bar on soft 16mm rear bar in middle.

Many many variables here, but set the front bar to stiff?

A couple things. Front bar could go to stiff, rear bar could go to soft. Personally, I'd set the rear to soft. I don't see the need for any larger/stiffer than the 15mm 2017+ on these cars for the rear.

Beyond that, look at your ride height and rake. Most people run a 1/4-1/2" rake at the pinch welds. You'll need more rake with a square spring setup. Less if you're running a staggered spring setup with like 5/7k or 5/9k.

Sidenote: What's everyone running for ride height in 2024? I've been searching over and over on here and it greatly varies. Earlier like pre-2020, people were running ~13.5" center hub to fender and it's gotten down as low as about 12.75" recently as a trend.
