200T + wheel studs

Hello,

Any people here who have fitted a stud conversion kit to their 200T?

I can find 2 options for M12x1.5;

- Pure Motorsport kit, overall length 75mm
Will these stick out further on the rear wheels? Or do you have to drill out the holes in the discs with a countersink drill?

- eBay, Watfields Limited, available in 68mm (rear?) and 75mm

I'll probably get the Sparco Assetto Gara 7.5x17" ET45 wheels for summer.
Standard wheels are 7.5x18" ET55... These will likely become my winter (and MOT) wheels.

Thanks, Glenn
