3000M with Minilite wheels

I sold the car about 4 years ago through our illustrious 'gamekeeper', I subsequently heard that it had been written off, whether thats true or not I don't know, however the wheels and tyres appeared on a TVRCC member's car and that too has since been sold on. I belive our 'gamekeeper' may have split them from the car prior and so they probably not involved in any alleged incident.

If it was written off, it was a sad end to what was once a great car!

You are totally right about matching rim width to tyre width, especially with modern rubber. The 225's on the rear were the narrowest tyre I could get to fit the rims, a wider tyre would have required arch modifications as well.

Adrian Venn supplied my shocks and poly bushes. He also corner weighted it last year. I spoke to Adrian about the wheels last week, and he said i shouldnt have any problems running 15inch MLs with 195/65 tyres, but he couldnt remember the offset needed.

[davidy]

You won't have problems with 195/65's but you will accelerate faster with 195/60's !!!!! (for gamekeepers benefit - assuming tyres are same brand!)

The car has a 3.9 rover v8 with hot cam, edelbrock manifold, racing flywheel and fully balanced, so the acceleration is pretty potent. I am changing to a salisbury diff due to the strain on the original triumph unit, and intend to get a different ratio to make the car a bit more long legged.

[davidy]

In that case are 195/65's putting a large enough section of rubber on the road for all that power!

Minus 5mm for a 7" rim. That Rover unit will produce a lot of torque and you may want to consider a wider tyre at the rear.

You have to get the offsets correct on the front or the wheel/tyre will hit the top wishbone on full lock. As for setting up the angles of the dangle etc, the best way is to drive it and play about till your happy/not destroying tyres.

Next time you have the chance*, get your car cornerweighted with a driver of your weight in the drivers seat (as well as getting the suspension set up). You will find it makes an enormous difference, you will then have a car that will handle directional changes the same left to right. You will surprised, I was!

*- having witnessed you fighting at the wheel at close range in the past, you will have a car that you can drive properly rather than drive through it's deficiencies!

Reckon its worth several seconds a lap to us amateurs!

I don't dare make any comment.....everyones right....as it was said lower tyre deflection, with the larger rim and lower profile requires a tighter setup ...I now a have laptop program that the 'driver' can put on his lap whilst in the car and on the scales.

You saying my bum looks big in this.

I used to use Compmotive ML's. Think they were 15x7". Tyres were Yokahama A539's 205/55/15.
Have a look at my profile pic - it looked amazing!

I'm running Compomotive ML 6x15 ET6 with Yokohama 195/55 15's - no spacers and no rubbing.

The diff is an XJS 3.6 manual Salisbury 3.54 - T5 Mustang gearbox.

300 bhp with a flat torque "curve" from 2,500rpm to 5,000rpm

Problem - First gear is nearly unuseable in the wet ......

My guess is the Rover V8 will have similar stump pulling characteristics to the 302. If you're going to use 15 " 55 profile tyres with the Rover I believe you can use a 3.08 diff and have a good spread in all gears.

I think I'll be going for a set of 65 profile tyres for the wet and see if that helps make 1st gear useable before changing the diff. - 195's of the front and 205's on the back.

I'll email you :-)

I reckon unless you are running very stiff springs (ie no spring!) at the rear that you will hit the arches unless modified) on full suspension travel with a 205/65 on a 15inch on the rear.

When I first bought my car it had 205/70s 14s on the rear (smaller roller diameter than 205/65 15s) and they hit the arches all the time.

Thanks for all of your responces. I spoke to Adrian Venn, and he is in agreement that 15x6 compomotive MLs running 195/65/15s is a good track/road compromise. I sprint the car, but i drive to and from the events, so still need somthing that will let me retain my fillings on the way home. Appearence wise i think the MLs look cool. Cant decide on silver or something else yet.
