I wouldn't say it will be too much brake, although it will be more of a bite and brake than an OEM mix and match. Closest comparison would be the RSX/S2000 combo but that's 5 lug and a larger rotor and caliper. The willwood setup is designed specifically for the cars with the super tiny brakes so it's not overpowering like it may seem. Sure it's a 4piston, but it's in a relatively small caliper. Spoon twinblocks are bigger than the dynalite caliper, and Spoon is smaller than almost any other BBK option. Also, if you opt for their 11" rear conversion kit, that too is designed to give a proper brake balance when matched with the 11" dynalite kit (this is what im planning on doing). This setup also keeps you from needing to upgrade the prop valve or brake booster. The rear setup is costly though. The fronts are a "best bang for the buck" sort of setup. Not the most elite brake setup, but not too damn shabby either.Sooo, Kerry... About your wilwood brakes, I'm debating getting a set since you always research and carefully choose your mods accordingly. Would that be too much brake for my hatch on the street? I'm thinking of just knocking that out and leaving the drums in the rear, I thought about the fast brakes 11" economy kit, but the integra calipers won't even use the whole disk and it seems like they are more for looks. The wilwood set up looks to be best bang for the buck.
If you really want to save money and upgrade, just get EX fronts and calipers with some nice Hawk pads, and Si or integra rear discs later on. On my EG, upgrading to SiR fronts was a night and day experience. The feel is more dramatic in the lighter weight cars than the stock equipped models.
