Shocks and Steering Rack Upgrade for RT4

[SGwick]

Hi Kartracer,

I just started to track my RT4 (still in break in period) but I also felt it was to soft and sat/rolled in the turns too much/long. I switched out to higher rate springs (based on weights and coilover angles) recently and my next trackday is on 10 July (so we'll see). I only do HPDE stuff (no racing experience) so not pushing as hard as you in a SCCA race environment.

Very interested myself to see if the higher rate springs without better shocks that can handle the increased spring load will make it better or worse.

There should be quite a few options for shock now with the rear being a coilover. Fronts will be a bit limitled. I have had great luck as has Grey65 with an offering from JRI specifically ordered through JJ Furillo at Ultimate performance. He can custom fab a front mount or adapt yours to hold cartridges in the front and their builder serials shock with work for coilovers in the rear. I love this set up on my RT3.
