I was just at Road Atlanta and talked to all of the brake manufacturers (SSBC, Baer, Wilwood) and although they have great products I was not happy with the price. So has anyone tried or is using the 4on4 system that Griggs racing is selling? If so how do you like it and was it really complete for $2800. I really need to upgrade my brakes and want the best for the money. Any thoughts would be appreciated. 91 gt convertible
