Big brakes and 5 studs

[Duke Thrust]

Hi all,

I'm back in a TVR after buying a 450 and I'm looking to upgrade the wheels and brakes.

I've a set of 16" RL7's from the Cerberas that I used for track days and fancy fitting them to the Chimaera. So, I need a 5 stud hub conversion, any suggestions as to a good source?

Secondly, I'm going to upgrade to the Ford 888 and 887 calipers to allow for 283mm discs. As I understand it the 4 stud standard fit 2WD Sierra Cosworth discs are the way forward. With the 5 stud hubs they clearly won't bolt on. Would the 5 stud Granada Cosworth discs have the correct PCD?

I have a feeling it'd be easier to get a nice set of wheels to fit the 4 stud hubs and just use the Sierra Cosworth Discs...

Thoughts welcome!

Ford 5 stud is not the right PCD.
We do these for 5 stud TVR's though...

Slightly O/T.

I have a pair of 16" RL7s that are shod with a nearly new pair of Triple 8s surplus to requirements if you're interested.

Are they 4 stud? (Already have a set of 5 stud)

Ah, just seen this.

They'd be good for a spare pair!

No idea if it's a good price, but in PH Classifieds.....

That'll be our friend Hans, nice guy to deal with and I bought my conversion off him. As for discs I redrilled my 4 to 5 stud using bench drill.

Are the centres on Cerbera wheels are the same as Chimeara wheels? (Working out if the Cerbera wheels will locate properly on Chimaera hubs)

email Phazed.....he has RL7s on his Chimaera

[Duke Thrust]

Got an answer from Hans, the spigot on Cerbera wheels is larger 71.6 and Chimaera is 63.4

Did you change your wheel bearings at the same time? If so, much of a job?

In summary, it's possible to convert to 5 stud........but quite expensive. New hubs, new discs, calipers and pads, new wheels and tyres for the road and the track.

You could get some really nice 4stud wheels and have a fair amount of change to buy us all a beer

I already have the wheels, I'm going to buy bigger calipers and new discs anyway so drilling them to 5 stud is a minor thing.

Also, I already need new tyres so really the only additional costs is the new hubs

Excellent

That really is 'Great Escape' stuff

I'd only do it with proper kit using a rotary table, not sure most bench drills are stable enough to drill accurately or mount a cutter to chamfer the holes after?

By the time you've done all that though, you are quite probably capable of making your own ally bells

still find myself wishing at some stage everyday that I had a big milling machine

Astonishingly I've just received the second set of calipers that the breaker assured me were stamped 887/888, these too are wrong.

So far I have a set of 063/5 with the other side being 070/5 and another set marked 9HF on one side, the other being obscured.

Both sellers swore blind they were marked correctly.

[Duke Thrust]

In fact, they're marked 889 and 890 respectively, anyone know if these will fit?

[QBee]

Everyone that I have seen who talks about doing the Sierra Cosworth 887/888 calliper upgrade is on 4 stud wheels.

Someone will be along in a minute who will know if 889/890 is the 5 stud version of the same, or some random different calliper. I don't, it's just my numerical brain rabbitting on.....
