rear brakes
 

I`m looking into upgrading the brake system on my GT. Is there an upgrade that will perform well with the 4 lug or do I have to change them out for 5 lug. I would like to stay with 4 lug- but I will need really good brakes- this car is my daily driver but I`d like to try scca someday.
Thanks

I dunno, I went with the M2300K13" and 12" 5-lug disks.
