325/30-19 19x11 +25 on IRS and 295/30-19 19x10 +25 Front ?

I'm getting into Auto X and HPDE so I want to get the widest tire I can at all four corners. My tire of choice is Toyo R888 as my car is a weekend driver that tracks once a month, I don't want to go 40-UTQG.I've freshened up the suspension and all the goodies underneath are fine. The car is Vortech boosted so putting power down is tough on 275 crap tires. I run in SM in SCCA, I don't really care about the class though I'm just out to have fun and go fast.

In the back I would imagine if you can run 335 width on an 18x11 rim with an IRS that 325/30-19 on 19x11 +25 should fit also. I can do the bolt grind and fender rol if needed.

In the front I think I can fit 295/30-19 on 19x10 +25.

Thoughts?

Why 19's if it's basically a track car?

I still take it to shows and cruise nights, so 19s would look better IMHO. I currently have 2K Cobra R 18x9.5s, im considering 285/30-18 R888s, but with a 24.8" diameter they may look awkward Or I could squeezee 305/35-19 R888s on the 9.5" wheels and try that, hey are 26.3" diameter which would look fine I think..

I have 305/35 18 r888 on an 11" wheel in the back. You're not going to get that on the front of the car. Putting it on a 9.5 will bow the tire and it will handle oddly. I run the 275/35 18 r888 on a 9.5 and it fits perfect. With a steeda bar up front, eiback bar in the rear on the soft setting, 375 lb spring coilovers in the front and 600 co's rear, the car is very neutral. Also have full maximum motorsports tubular suspension up front, full FTBR rear, no spare tire, and a Braile 11lb. battery where the back seats use to. The cars handling is insane. No need to try and stuff a 305 19 on the front.

On an unrelated note. If you're going to drag with the r888, I finally was able to coax some wheel hop out of it last night. 5,500 rpm 2 step launch on asphalt ha. So they can hop still, just a heads up.
