I think he is refering to the size and performance of the Type R 4 lug brakes. I think the 5 lug brakes are bigger, Atleast thats what i've heard. I personnally want to add the ITR 5 lug brake and suspension to my HB. The ITR brakes are more than enough for an Integra and especially a light weight civic hb. Most of the Auto X guys will tell you to just buy good pads and rotors for your ITR brakes and then spend the rest of your money on a good suspension set up. Thats my 2 cents I hope it helps you, Good Luck.
