A friend of mine recently bought a set after I advised not to. They were horrible. I asked why he bought them and he said, "Popular internet opinion". Now he's on R1s which still don't really work well on his car. I gave up on trying to help
Now, when I have people showing off their RRs, I just not and smile. It's easier.

hmmm... Not that I know of. I don't believe he's ever served (or could, actually).

Racefab do fabricated rear uppers. If they have enough adjustment for what you require is a different question though.

My tires stick out ever so slightly at static ride height. They tuck when the suspension is cycled. I'm guessing that's the same for the RS Motors car.

Is that the same car that notched the chassis to fit 315s?

Yeah, they fit the old falken 315 on a narrower wheel with some extra notching on the inner wall in the rear. Once you have trailing arms, the inner wall and shock become the next limit to deal with. In my car Im stuck where Im at because the Ohlin Flag canister is right at the rim but if I change that I would run a 5" spring, clearance the inner wall, and likely move wheel in about 10mm from where it is now.

Still not enough to fit a big 315 and wide wheel, but can narrow things up a bit at least.

Maybe. this car seems to have gone thru so many phases already. Those 315s in the videos dont look wide to me

It sure doesn't look like it. That car had the exhaust coming out of the headlight and last I saw, they were trying to do a 4B and SST swap into it a couple years ago. I don't think they've brought it out since ASM got heavy into doing K swap S2000s. That might be Brandon's car, I think he's ran it at OLA before.

i think i heard them say having 10k/12k springs with those 315s. I cant go that low with my 285/295s sets since I drive over curbs

lowered the car a bit


does anyone understand how these FA510 knob adjustments work? I had the rears at max setting but it seems to be going lower when I accelerate out of slaloms

Is it just a rebound knob? If you have it cranked you could be packing down and need to go looser.

single adjustable so I think its rebound and compression. some say its probably slow uncompressing the springs so it stays low(??)... is that what you mean 'packing down'?. I went 50lbs stiffer rear springs but for some reason the car is sitting more when i power out of slower turns. I'm thinking of going back to KWv3 rears so adjustments are easier to predict
