Hate to see what happens if a small rock or stone gets wedged between the caliper on Rim on that photo above.

 

i also agree, ive tracked my 500whp sti with little problems braking on my factory brembos. granite i dont run factory pads/rotors but rarely have issues. I run ferredo pads and dba 5000 rotors and have yet to have a problem with them

a bbk is gonna cost alot of bank at first and your brembos are more then sufficient to get the job done.

 

Interested to hear what the current brake setup is also...

 

I would be scared to track that car...Although the setup does look sick and it seems to fit fine you need to remember that wheels actually flex. There is a good chance that the calipers could hit the spokes in a demanding corner. Im not sure what the general rule of thumb for distance between wheels and calipers should be but that seems too close for comfort in my book...

 

I think AMS won a ton of Time Attack Events and didn't even wrong a BBK kit on their track car, I could be wrong though...

 

I agree with many here. A BBK is not often needed, especially after reading through the stats on your car. Let us know what problems you are having and we can see if there are cheaper, better solutions.

That is the same brake kit they use on the FQ400 over in the UK.

I would doubt alcon would make something unsafe, and I use the same brake kit on my car with 17" wheels an never had a problem racing.

 

what is the size of your discs???

 

If you are deadset on a BBK, Alcons are the best bet.
Stoptechs ST40s are awesome however not 6 piston. They are however lighter, use a larger rotor, and pads are cheaper.

 

3mm is a very good number to use for clearance. 2mm is possible, but bearing flex, wheel flex, wheel machining tolerance, wheel weights, etc., must be considered when the gap starts closing down. On the street, fine. But at the track things move around and flex a little more. With 3mm, no worries.

man, that is a tight fit.
