Bigger rear tyre size to change max speed.
Hi Guys - setup/handling question for an MK Indy R. I'm finding that running 195/50/15 is good for shorter straighted circuits like cadwell -
but if i change my rears to 205/60/15 my top speed will go from 118 to 130, which will be perfect for longer circuits like bedford. What other effects
will this have other than adding 10-12mm of rake?

Speedo ( if any ) will read low.
I'm addicted to brake fluid, but I can stop anytime.

Thanks for the replies. I know this locost shape has a reputation for being crap above 80mph but my car will easily approach the limiter at 118 in
sixth gear on partial throttle - I doubt 130 will overly bother it in areas such as the bedford straight and the quicker bits of donington, but only
one way to find out.
Have a speedo healer anyway so thats easy to sort. More bothered about handling effects of the additional rake - maybe it will make it even more
stable?

If you are raising the ride height of the rear of the car would you not find it ends up very tail happy?
Also, I would question what effect an increased sidewall height would also have on handling.
I have no idea about bike engines, but if I had the power and wanted to go faster I would simply fit a different diff. Is this something that is
irrelevant in your case?
