Recently had the RS-R coilovers installed and am pretty impressed. Build quality and packaging was top notch so a nice first impression there. Unfortunately the ride height was off/uneven out of the box, though the manual states it is set at the recommended settings from the factory. Still playing around with the ride height - as most already know, the FL5 fender shapes make the rear end look dumped when rake is flat. This is particularly true at the RS-R recommended ride height. I’m toying with a few mm rake to find a balance of looks while maintaining the intended handling characteristics.
Speaking of handling, I noticed a significant upgrade in performance, roll resistance and even some additional steering feel. Very impressed with how well it drives now - direction change is noticeably more direct than stock and there’s more grip. Most important is that all of the bounciness has been eliminated. It’s stiff (maybe a hair more than stock) but the dampening is vastly improved from Comfort through Type R mode, which is even usable on rough roads now. Note these coilovers maintain the EDC modes. I have the dampers set halfway between the middle and hardest setting for those interested.
I’m running KW V3s on my M2CS and in comparison, the RS-Rs are a bit higher quality in hand but I will say the KWs do offer a more solid feel while driving. Hard to say how much of that is the difference in cars but the RS-Rs feels like they were built by Lexus and the KWs by Porsche…not in terms of performance, but build quality…which I guess makes sense given where they both come from.
Only downside is there is a faint rattle coming from the front end of the FL5 now. Haven’t had a chance to really dig into it but sounds like it’s coming from the top hats. Will follow up when I determine if it’s a RS-R component or other. The RS-R upgrade also highlights some flex in the chassis so I guess that will be my next mod if some good bracing options come out.
