  • help with offset

    hi chavos i need some help a friend is selling me a set off rota wheels 18 x 8.5 offset +40 but i read in some place that oem wheels are +40 my question is the rotta wheels will hit the coilover? or i will need to use spacers?

    the wheels came with 225 tires front and rear

    Coilovers all vary, but an 8.5" +40 wheel will almost definitely hit the coilover in the front. My 8.5" +30 wheels were pretty close, and there was no way the gap was greater than 10mm.

        You should be able to get away w/ an 5mm Slip on spacer, I've seen 9.5+25's that only needed maybe 2mm more of clearance to prevent rubbing, a 9.5+25 ~ = to 8.5+38

        So you should be able to get away w/ a 5mm slip on but to be safe/sure a 10mm is abit more desirable...

          If you use spacers, best to also install longer wheel studs.

            Oh BTW here are some general guidelines for Max Back spacing: 155mm Front Max | 175mm Rear Max (They both apply to the S14 and S13 but the s13 has less Fender space)

                I would think twice about the Spec Clutch

                This is what I would be looking at:

                Fidanza FW
                RPS Sport Street Clutch

                  why you would think about spec? i got some friends using that clutch and they have no problems with it. sr20det ka24de and ka24de-t also a frien with a eclipse 2gen 380whp who used to change clutch frecuently he tried exedy, F1 ebay, and ACT

                      I think Spec's QC was (is?) pretty spotty.

                      That said, I've got a Spec clutch in my SR'd S13. It's been running strong for five years, no issues whatsoever. I did seriously baby it for the first 500 miles, don't know if that mattered or not.

                      My next clutch will probably be ACT or Exedy, and I'll get a light flywheel this time too. I really regret not doing the flywheel the first time around.
