I'm using the Moton upper perch but with the stock OE tophats.

 

I just installed these and took the S for a spin:


My first impression of the setup was that it is going to need more roll control... BADLY. I'll get the alignment done this week, top off the nitrogen in the shocks, then race it this weekend. I will continue to play with compression and rebound through the week, but I suspect it needs a big front bar or more spring or both. My brain is having trouble comprehending paying $600 for a front bar.

This will be my setup for the first event:
Moton Clubsports
anti-roll bars F/R: stock/none
ride-height F/R: 34cm/34.5cm (13.39"/13.58")
springs F/R: 700#/550#, 7"x2.5" + helpers
toe F/R: 0"/3/16"
camber F/R: 2*/2*

 

That sounds like a good starting point. I would recommend stiffer springs (min 750F/600R) and you'll need the FSB. The minimum would be about twice as stiff as stock.

I'll be running the R-S3s on the same wheels (949 6ULR finally) tomorrow.

 

Here is my initial set up.

koni yellow
600front 500 rear spring rate
saner middle setting
949 wheels w/ 255 hankooks.

will see how they are this weekend.

 

Does anybody else feel like the Hankook has a soft sidewall? It just feels sort of balloon-like when I push my finger into it. It reminds me of a mountain bike tire sidewall. My car rides better (less harsh) with the 17x9s and Hankooks than my stock wheels and RE-050s.

It may not a bad thing, I'm just curious. I've been running almost exclusively Dunlops and Yokohamas for the past three years and they are notorious for really stiff sidewalls.

 

Drive on the Toyo's once - everything will feel like a rock compared to them.


Seriously though - no I don't notice anything soft about the Hankooks. They feel crisper on a 9" wheel than the Dunlop or Bstone ever did on a 8.5" wheel. But thats probably due to the wheel width more than anything else.

 

My Hankooks feel pretty darn crisp on my 8.5's. This is coming straight from Hoosiers as well. They faired really well at the Prosolo this past weekend. I never felt like they were going off and got better with each run as they came up to temperature and pressure. I didn't have anyone to bleed my pressures between runs so I just set them 2 lbs lower than I run them and let them come up during the runs. I am not missing Hoosiers and stock class one bit so far.

 

what pressures are you running with the rs-3's?

 

Right now I am at 38 psi front and 35 psi rear.

 

Ok thanks, this past weekend I ran 35/32 and seemed to really like it. I'll try the 38/35 next time out
