Hey guys,

I just bought Essex/AP Racing BBK from URGE designs for my race S2000 AP1. The company lists the wheels that will have enough clearance for the BBK (with or w/o spacers) which are as follows:

• URGE designed CCW 18x 9.5, 10.5 & 11
• 949 Racing 17x9 +48
• 949 Racing 17x10 +52
• AP1 Front or Rear (20mm Spacer)
• Advan RSII 17x10 +50 (Evasive Spec)
• Advan R SII 17x9.5 + 25
• Advan RG III 17x9.5 +45 (5mm Spacer)
• BBS LM 17x9 +42
• Enkei NT03 17x9.5 +44/38
• Enkei RFP1 17x8 +45 (3mm spacer)
• Enkei RFP1 17x8 +50
• Enkei RFP1 17x9 +45 (25mm spacer)
• TSW Interlagos 17x9 +63 (10mm spacer)

• Volk CE28N 17x8.5 +30
• Volk CE28 17x9.5 +40
• Volk CE28N 17x9 +63 (10mm Spacer)
• Volk CE28 18x9.5 +22
• Volk CE28N 18x9.5 +40
• Volk CE28 17x10 +44
• Volk TE37 17x9 +22
• WedsSport TC105N 17x9 +35
• WedsSport TC105N 17x9 +49 (1 mm Spacer)

Is there a formula or a sheet to calculate the clearance needed for the wheels before buying them? I'm living outside the U.S. so it is impossible for me to check the clearance physically, I have to calculate it and then buy the wheels. URGE designs provides the following wheel clearance template (http://urgedesigns.com/aptemp.pdf).

I have no issues with rolling fenders, but I can't go for wider fenders (championship regulations).

I will be extremely thankful if you guys can help with the above.

i would email or message which ever wheel manufacturer you are looking at. send them the template and they can check brake clearance for you.
