[Troy]

Thanks for the tips on the tyres.

For the tyres, our local motorsport tyre dealer can supply the Kumho Ecsta V70A. They do a cracking 335/30R/18 R Compound for the back. I have run this tyre (245/40R17) previously with success.

Very sticky once up to temp.

Check them out. In most pics, they only show the narrower section, but these big buggers have an extra row of blocks either side of the centre rib.
