If you were to setup a twin to feel and act like a GT car, what if anything would you change from stock. Alignment, bushings, dampers, spring rates, ride height, wheel size, tire size, compound... Anything is on the table. I'm looking for something that can chew up highway miles with ease while also having rewarding grip and feel in a corner.

What I liked about my 2013 FRS's stock setup was that it was quiet and comfortable during most driving. What I didn't like was how easy it was to put it on the bump stops and thus how easy it was to get unsettled in a corner, even on the stock tires. I've made several changes since it was stock, and now I'm thinking it's time for a blank sheet approach. This time I'd like to add some science to the decision making process instead of just doing the same cliché things.

I'm thinking a simple set of slightly stiffer springs with dampers that allow more travel, some more caster to give more camber gain and feel, better tires that maintain composure when pushed, 17" rims as they're decently light and allow sufficient sidewall, and an assertive vice an aggressive alignment.

To this end I'm think the ever vaunted B6s for dampers.

I'm consider a couple of different spring setups. RCE yellows is an obvious choice as they increase the front spring rate a significant amount more than the rear. As the rear always seemed to behave well that seems logical. But I'm also considering a set of BRZ front springs mixed with FRS rear springs to keep as much travel as possible and as much comfort as possible.

Pedders strut mounts for the increased caster camber and better SAI, and whiteline control arm bushings for a little more caster without increasing NVH too much, and camber bolts for fine tuning.

Tires is a whole thread in and of itself, so I think I should leave that for now. But I'm wondering if tire width has any noticeable effect on NVH?

Stock or lighter rims.

For alignment settings I'm thinking ~Camber - 1.75 front - 1.25 rear, and toe set to zero everywhere.

Please critique any and everything here.
