Will say, 18" wheels and tires have a negative effect on the Type SH ATTS?

 

I'm not sure ...
I got 18" on mine ???
I only driven for a little bit ...
I really didn't have a chance to take it out for a hard run
because I am still breaking in the new clutch and flywheel ...

 

Are we talking hardcore performance? I don't think huge wheels are good for that anyway. Hmm i'm interested though, lets wait till somebody like ludeboom or something replies.

 

I don't know a lot about the ATTS system, but doesn't the computer read the speed of the wheel itself to determine how much power it should put to that wheel? If so, I wouldn't see where there would be a problem. The 18" wheel would have a longer rotation than the 15" for sure, but that also decreases the rotation of the rotors, hubs, axles, and everything else so I would think that in itself would compensate. Just a thought, though.

 

I was considering going w/ 18x7.5 Rota Subzeros instead of the planned GT3 16x7s. 18" Subzeros weigh in at about the same as the stock SH wheel and I was concerned about how the additional rotational mass on the outer edge of the wheel would slow down the actual rotation of the hub which I believe the system gets it readings from. Would'nt that slow down the response time of the system since it "sees" the hub spin slower than it normally would on a 16" wheel in a spirited turn? I just want to make sure I rule out any problems before considering anything larger than the stock size.
