RS*R Super Downs Installed (tons of info)
#16
The 235 Conti DW has a very rounded profile and a narrow tread which helps fender clearance by a large margin. I compared it side by side with a 225/35 Michelin Pilot Super Sport and the PSS was MUCH wider than the 235/35 Conti.
Almost forgot...the camber is NOT adjustable on the 3rd gen RWD (front or rear).
Maybe???? Or it could be J5 for less money????
thanks for the info. I prefer the drop of the super downs more than the regular downs and other springs out right now, but i want to run 19s when i eventually get some wheels. i was also wondering if possibly a 225 up front would help with the rubbing since its stretched a little more. i'm not sure if i want to pick up the rsr coilovers just because i had coilovers on my last car, and it rode super stiff, where the lexus stock rides so much better and don't want to lose the ride quality completely.

Exactly, i had BC BR coilovers on my 05 WRX and then eventually switched to air suspension. I guess now im back to square one figuring out what suspension i want on my IS... one things for sure the stock ride height has got to go

A 225/35/19 would probably help due to the overall diameter being a little bit smaller than the 235/35/19. Keep in mind that all tires are not sized equally on their width: https://www.clublexus.com/forums/is-...wered-3is.html

I echo your thoughts completely. I love the drop of the SD springs much more than the Down springs which is why I bought the SD's. I had some custom valved KW Clubsports on my last STI and they were pretty stiff. Add in the fact that I replaced all of the soft rubber bushings with harder urethane bushings , the car quickly because something that my wife absolutely hated. I don't want to lose the nice Lexus ride but I know there will be some give and take.

I had to drive into work today (200 miles round trip) which let me gain some more thoughts about the springs and the ride. Half way to work, I began to think that everything felt pretty damn good until I hit 3 large dips/bumps that bottomed the suspension heavily. It hits hard....I don't like it. Other than those 3 instances, it was okay.
I still don't like the appearance of the rear camber. I desperately want to fix this....sketching some ideas now. Camber adjustment devices on multi link suspensions are not simple.

Did you not cut any bit of the bump stops? Per Tein, I trimmed mine. The extra travel might help. My friend's e92 M3 has even less travel than you stock. My s2k on coilovers even moreso but you don't get the bone jarring feeling from hitting the bump stops.

Yes, but just basic instructions on the springs (e.g., bump stops).
