Why would it make a difference ?
The 5 stud pictures look like the genuine spider alloys. To see a picture of a griff or chim wearing 4 stud spiders shows how the bolas actually look on a non hub converted car.

im getting the jist you like the style, but
I'm not being anal, it would just be good to set a set bolted onto a 4 stud tvr.

So like Daz, I am liking the Spider wheels, but understand Rob's concerns....I don't think you can beat the look of the 18" genuine Spiders, but I think the Bola 17" B7 is a reasonable compromise. Went for the 17 x 7.5 option ET40 on front, ET30 on the back. I had a reasonable set of tyres so wanted to re-use these.

The drillings on the 4 stud fitment are literally that, with no blended holes as on the originals and somehow they don't look quite as nice as the 5 stud. They use the narrow wheel nuts with a slimed adapter. I am waiting for the correct nuts for the front as they protrude.

Anyway the wheels are well finished and am pretty happy with them, will get some TVR centres. Couldn't justify the 5 stud conversion and it allows me to revert back to the old Imolas at any time.

Not sure if there is a 18" version on the cards from Bola.

Anyway hers a few pictures and a direct comparison against the car previously posted which is a cracking example.

Cheers Pete

At last a photo of the real thing on a real Chimaera. Very useful, thanks.

Not available when I ordered and they replaced a set of 7.5" alloys that I was quite happy with, if they had been available I may have gone that route...

Those smaller dia nuts used on the bola wheels are referred to as tuner nuts. Don't know why tuner but it's the lingo the wheel places use.
Well bravo to the pictures posted above smile the 4 stud pattern does seem to detract from the initial look but the wheel style looks fine as a 17". I think the wheel nuts need to be a proper hex across flats type to make the wheels really sing on the tvr. The tuner type nuts look too slim in the smaller clearance hole. Perhaps a dark anthracite grey finished wheel with chrome hardware would work better with the tuner nuts?

Anyone know if the 5-stud conversion is reasonably easily reversed back to original?
If I was desperate to go to real Spiders, I'd still like the option to return to standard some time.

It's really this question that's making me consider Bola.

The pcd on the 5-stud is 112mm so you need a set of hubs with this bolt arrangement and matching spline fitting for the stub axle.

One conversion method was to take the existing hubs, remove the bolts and re-dirll. Not sure if this involves any fill work too.

Another method is to use Forf hubs with 114mm pcd (i may have got the pcds mixed around) and use concentric nuts to hold the wheel on.

If you have two sets of hubs then swapping them over is reasonably involved but not complicated.

Cost of conversion - probably more than the wheels.

Cost of swapping hubs back and forth £500 a time.

You have.. They are 5x114, Ford hubs are something else.

You need 4 of these to convert to 5x114

Have you used them?

I bought similar 'quality' stub axles and the machining was not good.

Secondly, would that would fit the earlier Ford hubs used on the Chim, Grif, S?

As far as I'm aware, the 5 stud conversions used Tuscan hubs as per all the last built tvr five stud cars. I've never done the conversion myself as the original tvr spiders are too wide for the front. Only one tyre size is suitable too so never felt the need for the conversion and put the money into the image wheels instead.
When you say machining wasn't good, in what respect? The tolerance is on the spline, bearing and wheel holding centre bore. The surface finish of the hub face isn't critical as long as it's running true and square to the bearing journal diameters. The original Ford hubs are just cast iron lol

The size of the holes have made me make a decision , the holes are far to small and have totally spoilt the wheels .

The only good thing about those style bolts is they won't damage the wheels when fitting and removing.

Its a bit of a let down for me.

If you fiited proper studs is the enough space for the socket to fit ?

Yep those tuner nuts don't really work when compared to the original style nut, even though the wheel looks good. Strange how such a simple change can effect the look of the fitted wheel.
Be brave and go for those big chunky five spokes smile
