Just got the Cerbie 6-spoke alloys onto the 400SX. They look pretty good. I had to shim out the rears a little to avoid fouling the tie rods but only by a few mm.

I'll report on the handling in a few days but initial impressions seem fine, although it subjectively feels a little lower at the rear.

These ones have had the wheelnut seats machined so that there is no lateral stress on the studs.

One day when I get my self organised - I'm going to swap the TVR 18 inch wheels from my T350 to the SEAC.

Just to see how it looks and whether they fit.

Looks nice! I changed the oz's for 17 inch borbets and going to fit high quality spacers to get the ET value back to original.

From the title I thought this was going to be some sort of contortionist thread

When fitting alternative wheels to a wedge what numbers do you need to know?

PCD of studs
Rim diameter, width, and Offset
Anything else?

Obviously rim diameter and width are to some extent choice within the limits of what will fit so my main question is what should the PCD and offset be?

Hub centre diameter. Not a huge issue, unless its too small and doesnt fit over the hub nut, or the wheel doesn't take taper faced nut to locate the wheel on the axle axis

So what would it be like with the Cerbie 'Spider' wheels - maybe in the same colour as the body?

What is PCD?

You also need to check that it doesn't foul the fuel tanks and rear tie rods at the back and the GRP bodywork at the front on lock. problem is that these do and can vary from car to car as the body/chassis positioning is not consistent.
If you run spacers you need to tell your insurance company as that is considered a mod. Some don't like it because of previous bad experiences.

PCD = Pitch Circle Diameter
It's tech speak for stud pattern.

Anyone got any Wedge specific numbers for PCD, Offset, Hub centre diameter etc?
These can obviously be measured off of the original wheels but that makes the sweeping assumption that the ones on the car are original and correct.

As it is my front tyres (205/60 15 on 7J rim)just rub the arches on full lock anyway.

Looks nice,

but can't help it will always be a split rim fan of wedges and 4.3 Griffs.

Yeah the split rims are in the shed now having been cleaned off with rainwater. They'll be coming out in the summer for BBWF. No sense in getting all this crud on them this time of year.

Steve - I had to ring the insurance peeps anyway as the wheels themselves are non-standard.

The tie rods on mine were the closest at the back, fuel tanks were fine. I might investigate a lock stop for the front to prevent fouling there on full lock.

Stud PCD is 112mm. These Cerbie wheels are modified to suit this.

Offset should be "enough to clear the front inner arches and rear tie rods, but not so much as to foul the wheel arch flares under full bump"

Once more empirical data is determined on offsets, I could machine some permanently attachable spacers to evade the insco not liking separate spacers issue. This would also have the benefit of providing a more positive location for the wheel onto the hub if recessed in the right way.

So far so good - just had a full-power sprint out of a village with notoriously slippy muddy road. Normally with the old 225's on the back I'd get wheelspin in 3rd and probably 4th, even on part throttle, but with the 245's the power went down great, no wheelspin.
