At the risk of being crushed by the forums collective knowledge and opinions, of which there are many ,I did have a look at the front rotor question with respect to current Wilwood products.
The best Hat option would appear to be
The PCD , Hub center and offset appear to be spot on. The application note says this is a Pantera specific part. It is similar to the blank hat but with all the hard machining work done and all the dimensions seem to line up .I could not find the face thickness to check that dimension, but we should be grateful Wilwood are offering this product.
Remember you only have to buy the hats once !
Rotor options are available in either 0.81( 3 off) or 1.25 inches ( 2off ) .
Here are the 0.81 inch by 12.2 inch rotor options to match this hat:
Here are the 1.25 inch by 12.2 inch rotor options:
The four piston FSLI Symmetrical Caliper dimensions look like they will go on these rotor widths and still fit in a 15 inch standard rim.
The 12.2 rotors are 6.1 inch radius plus the caliper clearance gives a 6.85 outside clearance requirement without andy gap.
The inside surface of the std 15 inch rim at my best measurement 14.35 inches giving a radius of 7.18 inches. Anyone else with another measurement on the inner diameter please speak up.
This should give just enough clearance ( around 5/16") for the occasional adhesive wheel weight to go rocketing past.
You can get these to suit both rotor widths
0.81inch width with a 1.25 inch diameter pistons
1.25 inch with 1.38 inch diameter pistons
I did have a look at the six piston dynapro options :
At an outside radius of 6.97 inches on the 12.2 inch rotor you only have around 0.2 or 3/16 of an inch. Not enough for any wheel weight clearance and getting pretty close to the nelly, but a miss is a mile!
These are all straight off the shelf - no machining required.
Lemans will probably let us know down the track !
Cheers.
