Track wheels wanted

[DeanoR1]

I'm after a set of 4 x CXR wheels to fit my MK Indy (sierra hubs), or Team Dynamics. Must be 13". Does anyone know the widest tyres that will fit on these wheels with no clearance problems (R888's).

[jeffw]

depends on the width of the wheel.

I've seen one hillclimb prepared car which was running 8.5 x 13 and 9 x 13 cxr wheels with 215/50R13 and 235/50R13. I'm hoping to run in the HSA Chsmpionship next year and looking for maximum mechanical grip.

[jeffw]

Team Dynamics are only 7J. I run 215/50 13" Avon ZZRs on 8J rims. They are the same size as the Kumho 235/50 13" (physically the same size) so you probable don't need to go much over 8" to get the tyres on. HSA Championship is very competitive so good luck.

You may want to look at http://www.force-racing.co.uk/wheels-13/ or http://www.mb-racingwheels.com/13_rims.htm

Has anyone fitted Hi-Spec 4 pot calipers under 13" CXR or team dynamic wheels, if so, what size discs do you have. 260mm?

[jeffw]

260mm sounds large. I'm running 247mm (I think) on Wilwood Midlites with CXRs.

i had a feeling that Caterhams ( 13 inch wheel ) use something like a 247/250disc on the front?

[jeffw]

Sounds about right.

260mm is 10.2 " so a bit of a squeeze in 13" rims.
