Just an FYI. A 305/45R18 Mickey Thompson ET StreetR will fit on a stock 18x7.5 wheel that's been widened 2". I just had to remove the upper shock dust covers and use a 1/4" spacer that I got from Rough Country. Had the wheels widened by WeldCraft Wheels out of Michigan; they did a great job on them.

You wouldn't even know there was a drag radial on there if you weren't looking for it.

Nice. What kind of power you putting down to need a D/R?

 

Haven't been able to dyno it or get it to the track yet, but it appears to be trapping somewhere in the 105-107mph range in the 1/4 when running at Da Pad. So on this tune probably in the 450-480ish range at the wheels. I have a Killer Chiller here to put on also. Once it's on I would expect to see about a 40ish rwhp jump. It pulls out a lot of timing due to heat. Plus I can put the bigger tune in then, which I'm hoping is about 550ish at the wheels.
