Sorry for the delayed response Sam, thanks for the detailed reply!

I am only planning to track it very occasionally and have zero track experience so probably will never notice. Given all of the I've convinced myself that I need to go all out and get a set of BBS CH-R 19x8.5s in ET48 to minimise any issues and save some weight (BBS 24lbs vs VMR 26lbs) while maintaining the 19inch look. Now just to save the funds and convince the misso! Can't believe I can get the same wheels shipped from the UK for ~$500 cheaper including GST than I can through Jax Tyres
