Hey guys, I have an S650 with a Whipple Stage 2 and a few other goodies. The car dyno’d 761 whp on pump gas, and I’ll soon be testing the return-style fuel system with E85 and a 3.5” pulley.

As far as suspension goes, I’m running all Steeda parts: Ultimate Drag Stop the Hop Kit, front G-Trac brace, differential bushings, and progressive lowering springs (rear camber arms are on the way). The only exception up front is that I’m using Maximum Motorsports camber/caster plates. The shocks are the stock Performance Pack units.

The car is mainly used on the street, but I take it to the 1/4 mile about once a month. The track we run on is very poorly prepped, since it is actually the main straight of a road course, so traction is marginal — basically like racing on the street.

I used to run M/T ET Street Rs, but I’m now switching to 28x10 Hoosier bias-ply tires because I think they may help with traction.

My question is this: the alignment recommendation I’ve received for my setup and use case is the following:

Front camber: -1.00°
Front caster: 6.90°
Front toe: 0.00° total
Rear camber: between -1.00° and -1.50°
Rear toe: +0.12° per side, +0.24° total
Thrust angle: 0.00°

What do you guys think of this setup? What would you suggest to maximize traction on launch, considering the way the car is used and the type of track we run on?

I would think you would want your rear camber and toe to be almost zero for the best contact patch. All of the parts you're installing should stiffen up the suspension and minimize deflection.
