what type of brake discs do i need to go with my wilwood powerlite calipers and sierra hubs wanted drilled and grooved or just grooved where is best to get them from?

mnr will sell them no doubt. i got mine from there but for raceleda front calipers

Have a look at the dimensions of the reccomended disc, then use THIS link to see which cars use those dimensions, then check ebay and generally everywhere online to see if you can find them cheap!

I got some red dot drilled and grooved, new, for £10 on ebay in an auction so it's possible to get some good deals
