Got some new wheels, they didn't clear the brembos even though the dealer guaranteed they would. Anyway all sorted at st George tyres with a good deal on a set of 18" XXR 550s. Fronts 8.75 +36 with 255/40r18 rears 9.75 +36 with 295/35r18. Nice wider track, surprised how well the invos grip even as a new (under 500km) tyre. Could still fit an 11" wide with 325 in the rear pretty easily I think. Also tidied the engine bay up a bit, moved the catch can under the intake manifold and fitted new lines and fittings. Then used the old catch can bracket to fit a new overflow tank.
