tkb289 Tim I don't know the pricing differents between the 2, but outboards are on my list for down the road. I 98% roadrace and autocross and 2% drive on the street.
If you are going to autocross, the brakes not get hot enough to have any problems.
Roadracing is a whole other issue. High speeds, hard braking, boiling brake fluid all can happen. Brake pedal gets spongie. Alot of heat get builtup with inner brakes and differential. Running duct work has helped but running hoses and fans work better to remove the hot air. Don D. had the best setup with a snorkel to cool the rearend and brakes on the car.
I am still running the first set of brake pads on both first and rear of the car. I do have the 12" rotor kit from ERA and it works great. What tires and wheels are you looking to run? 15" or 17" ? I started with 15" and now run 17" pilots. They work very well for being 5 years old. I do use VHT to keep them soft. Maintainance is a big thing to getting long life out of any parts on the car.
As far as the handling issue, Tim that's a whole different issue and would take another thread to talk about. ERA setups the cars to drive and handle for all around usage. If you are serious about racing, you will need new springs,shocks, 5 point roll cage, remove the windshield to not crack it at high speeds, accusump 3 quart tank to help with
oil pressure on high "G" turns.
I am happy with all the improvements that ERA has helped me with and improved the handling of the car. The more important thing you might want to look at is-------------------------------------power steering. I know it's not manditory but it's real nice have. Easier to drive when racing or on the street. Rick L.
