I have Bremsport calipers on the back of one of my cars and apparently they are made by Outlaw in America and use the same pad as the Wilwood Dynalytes which is a bit of a result as I didn't knw where to get pads from. Apparently their calipers are rebranded for several different companies but they are a nice piece and have been on there for ages now.

Funny you should say that Goran I believe a lot of guys go over the top on brakes. I have modest sized (303mm) GM LE1 discs all round on my IROC with Wilwood Superlites and Dynalites and I have to say they have never given me any real cause for concern especially as I race on treaded tyres. I often wonder if the weight of a larger disc/caliper would be counter productive. On my older car I have the same discs but massive Wilewood GN 6 pots up front and the Bremsport/Outlaws at the rear and yes I could lock those up at any speed as I have to run on a treaded 8" wide tyre and IMHO they are overkill! BTW I am into my 3rd season on a set of pads on those so maybe I am not trying hard enough !

Just wound off some of the camber on my old car to try to stop front wheel lockups at Snett this weekend, it was wrong anyhow with 4 degrees on one side

It's a model specific tool for MX5s, but I thought this tool might be of interest, with regards to things like brake bias, pedal force and temperatures:

My Wilwoods still giving good service on both cars, I went to EBC Orange pads briefly as no Wilwood pads available at short notice, never again, the things actually melted through the back plate and the pad collapsed it contributed to a crash I had at Donington as I couldn't pull the car up at the chicane, back to Wilwood now!

Personally found better results with Hawk over Wilwood pads (use their calipers though) but yes, EBC are not for real racers...
(Although I used them 10 years ago on my Suzuki GTi, but that was 850kg all up and about 100hp at the wheels, so brakes were not an issue!)
