Tire height for roll racing

[MustangPP1]

What tire height do you recommend in the rear for a 3.55 gear 10 speed car? This is for roll racing and 60-130 testing, no digs. Looking at either 315/35/17 (26") or 305/45/17 (28"). Lot of mixed reviews, let me know!

26" sucks for digs and rolls with 3.55s and the A10. It also looks stupid. In my opinion.

I run ET street Rs 305 45 17.

What about weight? Getting less mass in motion also means your acceleration will make a notable improvement.

Unless you're pulling seat belts, random bolts, it's not gonna have a huge affect. Bias ply will be a lot light but have more rolling resistance.
