I love the way the stock brakes on my 98 stop. They exceed the stopping power of my track setup 86 MR2.
What does concern me is that the stock rotors do heat up very fast. They do recover quickly, but on very fast downhill fast road drives they do get weak towards the bottom, which can be un-nerving.
I have researched the many big brake options out there.
Having been doing this car thing for the last 25+ years I know \how fads are and what to stay away from.
One of them is the fact that a car as light as the ti with under 150hp, and only used on public roads does not need huge brakes to staop safely. I also Know that bigger brakes can also add to unsprung weight which can slow the car, which I want to stay away from.
So knowing all of that, I have not been able to find vented vs. unvented front brake setups. basically early 98 vs late 98/99 brakes.
My car stops just fine. With proper pad selection and fresh undrilled/unslotted rotors the car can make my ears pop when stopped.
Upgrading to the vented rotors and wider calipers -
1. Does it help on prolonging brake fade due to rotor heat build up? In theory it should, but in real world does it?
2. What are the parts required to do this? I am pretty certain that the Calipers (and maybe the caliper brakets - unless the stock 98s will work) pads and new rotors are required.
3. Pads. I use Porterfield pads on all of my performance cars. I wont use any others, unless they are OE pads from BMW. Has anyone compared the two?
4. Direct real world and track comparrisons of the unvented rotors vs. the vented rotors?
5. I will be replacing all of the Rotors(BMW), and brake pads(BMW or Porterfield) on my 98 ti m-tech. What else should be changed when this job is done? I see mention of sensors. Can I have more info on these and why they should be changed?
thank you in advance
