If you plan to compete in STX you may want to consider skipping 225s and going straight to 245s or 255s with a 9" wide wheel to maximize your chances.

I run B8s with RCE Yellows and I am also quite happy, but I also run different tires and wheels and a lot more camber as well.

Thanks for the feedback! Glad you got your alignment sorted, now it's time for some real tires. ;)

We designed the RCE Tarmacs as a small step above our RCE Yellows in performance for those that want a little more edge while keeping a fixed perch damper to keep things simple. Not really intended for stock tires...we expect most would run them with a stickier summer street tire. Also designed specifically for aftermarket dampers like Bilstein or Koni.

Our RCE Yellows are softer and more of a OEM Sport+ option that can work well on stock shocks for a DD and some light auto-x or track time. Still a good handling spring and perfectly fine with stock tires or something a little stickier. Better ride quality with those but the Tarmacs will handle better.

Yes Bilsteins do seem to soften a bit after install. I think the B8s are a good shock (love the gas pressure) but I wish that they were not shorter in overall length. Makes me consider B6s as the better choice BUT those probably have a longer bumpstop internally, so the B8 is probably the way to go.

My plan is that when my stock struts blow on my car (let's hope not soon), that I will add B8 struts to my RCE Yellows. Is this too much and it'll be a waste, or will the Yellows do even better with the B8's? By that time, I hope to have graduated to 18 inch wheels and better tires also.

That's not a bad plan. :)

What do you use for camber adjustment? How does the ride feel? I'm RCE Yellows with stock struts now, but will probably do your exact setup, wheels and tires included, sometime down the road.

What I have noticed now with the stiffer suspension, is a significant increase in drivetrain movement when shifting between acceleration and deceleration. ... I will instead probably work on securing the drivetrain in ways that will keep me legal for the STX class of AutoX.

Raceseng cascam plates and SPC rear LCAs. It rides fairly well but our roads here are crap and I couldn't take it everyday so I no longer daily drive it, and drive a beater everyday instead.

From what I understand of STX rules, upgraded bushings are fine so long as the amount of metal in the bushing doesn't increase. I.e., TiC's Delrin steering rack bushings are allowed, while TiC's aluminum steering rack bushings are not.

With that said, drivetrain bushings are an easy kill. Whiteline transmission insert, diff collar inserts, and rear subframe inserts will do a great job of keeping things from flopping around.

Once A) I have the funds again and B) I determine the order I want to progress with my mods, I'm looking at Raceseng top plates and Whiteline rear LCAs.

Out of curiosity, what are your rear camber values with the B8/Tarmacs?

Do you need top plates for just springs and the B8's or will camber bolts do just fine? And then SPC LCAs for the rear.
