New Wheels and Tyres on SD1
I'm wanting to upsize the wheels on my SD1 from 14 x 6 to 15 x 8 inch wheels (minilite style).
What offset should I go for - I believe standard is ET40 so I thought 30 may work well, remain flush with the bodywork and clear the suspension struts.
I was thinking of fitting either 225/55/15 or 225/50/15 tyres - which would look best and are these likely to cause problems on full lock with hitting the front Vitesse deep chin spoiler or front guard?

The standard Vitesse gets close to tyre rubbing on full lock. The cars I've seen with larger tyres have rolled arches.Robrover wrote:My current wheels are GBs (Minilite lookalike) 14 x 6 and tyres are Toyos 215x60.
It goes fine but 14 in diam performance tyres are not easy to come by nowadays and I'm limited to Vitesse brakes.
The existing set up was fitted when it was 3.5 with a 3.08 diff; now it's 4.6 with a 3.45 diff.
You can fit XJS brakes with Vitesse wheels - a very worthwhile upgrade.

Assuming you have a .76 overdrive in 5th that gives you about 30mph/ k revs in top and 166 at 5500 revs, or 23/ k revs in 4th and 126 in top at 5500 revs, about right for a 10 to 11 second car crossing the line in 4th gear between 125 and 135 mph .
