Question Changing from 98 to 108 PCD?

Hi Alfisti

I have a 116 series based project car which runs on 98 PCD wheels. I wish to fit the depicted GTA rims in a 15 x 7 size, but they're only available in a 108 PCD.

I recall someone used to do these in a 98, but seems that they're discontinued now. Modifying the hub flanges at the rear to 108 is no issue as there is adequate 'meat' on the flange to re-drill studs to fit.

The front, however, is more complex as although there is also plenty 'meat' on the outer hub, the studs will need to be pocketed into the back flange of the brake disk - if I still use the standard disks.

I have access to a mill and rotary table, but first wish to avoid any unforeseen pitfalls. Has anyone successfully done this re-drill before? Can I substitute the disk with an older 108 PCD version or other type?

Any advice would be most welcome, thanks

For the disc you have to check the depth and diameter. I do not think that can be done. MTEC brakes used to supply a redrill service when ordering new discs. Maybe they still do that. Or just do it yourselve, not a very big deal I think.

Thanks, Veep. I'll just muddle my way forward on this one, but am sure I'll find a way...
