Brabham BT-38 wheels

[Paul S]

Can anyone point me in the right direction??? I am looking t replace the existing wheels on my car but I cannot find a vendor who has replacements. Lee Chapman had them but has no stock in the sizes I need. MB-Racing wheels in the UK made a nice three piece reproduction but they appear to be out of business???

Thanks!!

Yes, MB shut down right after I sent him final dimensions for a run of 1979 four spoke Dymags. Rumor has it that someone else bought the business. Image wheels in UK have a model LM4 if that's close. Image built us the Dymag replicas.

I received a message from someone associated with them??? Hoping it leads to a contact who has the molds for fabrication.

He had the Dymag centers in stock and ready for machining, and then.......................................

I also had been in contact Mike Barnby and sent in sketches for Brabham BT21C wheels. He had the material on hand and I was trying to order a set when the website went down. Just recently talked to James Denty of Peter Denty Racing and he confirmed that Mike has sold the business. James is working with the new owner to try to get me a set of 3-peice wheels. I'll let this forum know if I am successful.

I just ran across an add on the racecarsdirect.com website. It seems a person named Greg Caton has purchased MB-Racing wheels. The add said: call Greg Caton now to discuss your requirements on +44 (0) 1622 858336 or email: greg@g-catracing.co.uk

I was able to get wheels from G-CAT Racing in the UK. Received them a few months ago but just got back home for the holidays to try them on. They are 3-piece wheels with Brabham style centers. When I checked to see how the centers fit I found they would only go partially onto the wheel stud threads.

I double checked my wheel stud centers and found them all 4" +/- .002". I also checked the holes in the wheel centers and they are also very close to 4.00". When I tried to put a 3/8" AN bolt into the wheel center holes I found that the thread would go in but not the grip area.

I'm going to get a 3'8" expansion reamer and widen the holes. I'm a little disappointed because the wheels cost $3720. I'll send a report in February when a finish my job assignment.

I finally got home and worked on my wheels. The front wheels fit perfect as received. The rear wheels were a different story. I had to ream out the holes on the rear wheels and that helped. The wheels would still not completely seat against the hub. I found my original wheels also would not seat completely either. I returned my rebuilt hub assemblies to the shop and we found the hub center shoulder was slightly oversized. After turning it down to just under 3.00" we found the counter bore on the wheels for the wheel stud lock nuts were too small. After increasing the counterbore diameter the wheels finally fit.

The overall quality of the wheels seems to be very good. I suggest you make sure www.G-CATwheels,co.uk completely understands the dimensions you require. I think most of my problems were on my end and not the wheel manufacturer.

Devillo: When you get a chance, can you send me pictures that show both the front and rear wheel outside centers.
