Spent quite a bit of time tonight going thru all the Extreme Summer and Track tire specs.

Couldn't find proper F/R sizing for a set of staggered 19s to work and be worthwhile vs 18".

However, the R888R comes in a 295/30/18. The 295/30/18 would fit, but is still 1.3" shorter diameter than the stock rear and 0.3" shorter than the 265/35/18 front track tire. 1.7" more rubber on each side in the back, but seems like this wouldn't give the ideal F/R handling balance.

The R888R also comes in a 315/30/18. I'm guessing this won't fit in the back, but I've asked Apex if they think it could fit on their 18x10.5 ET40 FL-5 or one of their 18x11 ET44 wheels. That would give a massive 2.4" more rubber on each side in the back and gets the rear diameter closer to where it needs to be (25.5" vs 26.3" stock).

Couldn't find a good 305/30/18, which would be ideal.

Will let you all know what they say.
