1M Track Wheel and Tire setup - more rim width and more rubber!

HP Autowerks, Inc. has put together a nice 18" track wheel and tire package that adds another 0.5" of rim width to both the front and rear of the 1M, making it 9.5" wide front and 10.5" wide rear and mount 265 front and 285 rears respectively.

Here is a few quick iphone photos...

Last photo is with AST 4200 on Swift springs.

Very cool. Any notable difference in acceleration?

How does it ride differently?

Although the wheels and tires are wider, they are lighter than oem wheels/tires. The car feels a little quicker while accelerating and more agile in the turns. As for ride quality the PS2's ride better than the RS3's.

Hankook RS3's shaved to 5/32 depth.

I look forward to seeing this project progress
There was a lot of fender gap to start with. These wheels/tires aren't much smaller in diameter than stock.

This set up is just for fun! For competition I would go with 10" front and 11" rear with 275 front and 295 to 305 rears. Always shaved as the tires will be heat cycled out before they are worn out. Plus there is less tread squirm and heat build up when shaved. RS3 is one of the fastest tires in Redline Time Attack street tire class. AD08's, Starspec's and RE11's are a few tenths off of the pace.

Depends on how aggressive of a setup you would like to run, square or staggered....

Look good.

I'm already running ARC-8 wheels on my M Coupe and am planning to move them over to my 1M when it arrives in 6-8 weeks.

Initially, I'll be running 255/35-18 front and 275/35-18 rear, but will try to wider rubber down the road.

The wider ARC8 wheels are 19-20 lbs each. I have not weigh the wheels only on the 1M, but my guess they are in the mid 20's.
