As far as shocks/struts go, there isn't much besides going custom.

One sorta plug-and-play option is to pick up a set of H&R coilovers, fab some stock spring perches, and have them revalved by Bilstein(around $75/corner). The non-adjustability and entry price of them at first glance sucks but I'd imagine it being a solution that is somewhat cost-effective. The total extended lengths have to within +/- 1" of the stockers so that must be checked out.

Part of what I do for a living is force measurement setup, calibrations, etc. so validating the stock SE spring rates are no problem.

I have a set of Intercomp pads that I can use to forward whatever corner weights are present using stock perch heights. I would expect motion ratios in front to be just under 1:1 being a McStrut. As far as torsion beams go, I'm in the dark as far as calculating any kind of usable motion ratios.

Talking base Mini Coopers, yes some have EDLC but like Jason mentioned, on Hoosiers, I'm uncertain if it provides a solid advantage. Fortunately I have some of the best HS competition in and around our region so the measuring stick will be real.

I hate bench racing and just like to go at it.

I'm open for other suggestions regarding shocks/struts.
