You'll soon be looking for the 23mm MB master cylinder. Now tires: You going to run some DOT "racing" rubber or you going to slicks? If slicks, how large? From practical experience, I've learned this is important. What are you going to do with the suspension? Once you upgrade the power (go-fast) and the brakes (stop), are you going to work on the suspension to stop the front end dive that's going to upset the car's balance when you decide it's time to stop? Don't know how much time you have on a track, but when I was instructing, I ALWAYS told the students to learn with the engine that came with car on the hardest tires available (car control) before they began upgrades. The car will talk to you. If you do all these things without the practical learning experience, you mask what the car is trying to tell you and you set youself up for "issues" down the road. Ultimately, it's your money and your car. Buenos suerte.
