Square is the way to go. You need all the front end grip you can. Plus you have the nice advantage of easy tire rotation, etc. You could go bigger than 295....the only limiting factor is wheel width, which can't be changed. You can space them out 1/4" on each side.

He doesn't have "coil-overs"...he has DA shocks. You have to retain the relative position on the shock and the stock springs.

My BSP set-up:
Suspension:
Motons with 900/750 hypercoils
Factory A-arms with offset bushings
Hotchkis front bar (full stiff)
SPL Endlinks
No rear sway
Alignment...info to come

Engine:
Pop Charger w/80mm velocity stack
Samco Intake tube
Z1auto 3" MAF
MD 5/16" Spacer
UR Crank Pulley
Z1 2.5" Test Pipes
TurboXS Y-Pipe & Exhaust (only weighs about 19lbs...too my surprise)
Tomei V2 Headers
Tuned Osiris/Uprev by Hills Garage
Will be converted to E85 once we get summer blend in MD (June)

Drivetrain:
Cusco RS at 80% lock
OS Giken Super Single w/Aluminum Pressure Plate (Pretty light....~25lbs for the whole assembly with flywheel)

Brakes:
Stoptech 332mm front BBK (2 piece rotors) and stock rear non brembos
Stoptech lines
Stoptech pads

Wheels/Tires:
ARP Studs
18x10.5 +15 RPF1's
315/30 Hoosier A6's
Will be upgrading at some point in the year to 18x11.5's or 18x12's.

Aero:
Work in Progress.

Weight:
2919 w/no AC or Radio....hoping to get that below 2900 before Nationals.
