Im tracking my car in 3 weeks. I wonder if I should get these now or test the stock brakes to see how they hold up?
I strongly urge you to get dedicated track-only compound racing pads.
Not only will you have more confidence that the compound is up to high temps, but you will enjoy the experience much more with solid reliable braking.
In addition, you won't be having to replace your street pads very quickly.
I used the Porterfield pads mentioned here for a while on my previous car, and (1) the pad compound wasn't up to the high speed / repetitive braking, (think squirming under braking - not a great feeling), and (2) about 1/2 the pad was gone after one day. The first time I used track pads, I slapped my forehead at not having done it a lot sooner.
Note that this is not to say that you will have the same problems with the Elise (it's a different car compared to a 3rd gen RX-7), but the peace of mind alone is worth it.
Also, to be totally clear, I would have no problem using the Porterfields as everyday street pads. I just would go the extra step to get dedicated track pads for track days. Porterfield even makes a race-version of the R4 pad (R4-R, I think).
