I dunno if i am classified as stupid or not and i am not a mechanic or engineer, but i do not understand some outer guard clearances that i am seeing in pics compared to what i am experiencing. i have (hr disc front) standard commodore wheels 6" with 205/65/15 on hq stubs/rotors (redrilled). on full compression and lock hit the outer guard while also narrowing track due to their width. With this diameter tyre it is perfect for my speedo with supra box and 3.7 vn diff ratio. i understand its slightly oversize than original. Was told by Bob Jane that there are no smaller tyres to fit the rim legally(load/speed) true?? but told i could go 215/55/15 for correct diameter but that is pushing the tyre further into outer guard, ??  I see many members cars (eg smithy) with 17''s and the outside edge of tyre/rim sit heaps further out than mine. Doesn't this cause outer guard clearance issues?? id don't have rack and pinion steering but if i did would it mean that i could only turn the wheels about 10 degrees?? Some of these pics i see it seems as soon as you turn the wheels your tyre is under the guard with less than 30mm to spare. do these guys have suspension that will never compress more than 25mm?? Will it pass engineering? If so what is the point of bump stop clearance?? I could go back to hr stubs but that would be narrowing the track even further with commodore wheels. Do i have to fit old 14'' commodore wheels?? can someone help cause i'm at a dead end. How can i get exact track if necessary and guard clearance with commodore wheels even if i get custom offset?? 

Love you guys
Chris

Hi ken i am running standard hq stubs with hj brakes up front with vn rears (xb master and gemini booster). Front discs have been redrilled to commodore pattern. Like others i havn't made my wheel choice early but i am looking at speedy malibu's 17 x 8 with 215's which are +48mm offset. This will push the outside of the tyre in about 3mm compared with standard 205's with +40. This still however wont be enough. I got a mate who makes polyurethane bushes so am gunna get a couple of taller bump stops made up i think. any problems legally narrowing track a bit?

Chris

Thanks very much michael. With your setup did you have to run an adjustable proportioning valve. On hoppers site they say maybe no valve is worth ago. I don't want to muck around but they are pretty expensive. Did you have any problems with outer front guard clearance?? do you know anyone in brissie who do custom handbrake cables?? sorry for all the questions but you seem a good person to ask.
cheers chris

Hey guys just wondering if anyone knows of a good engineer (knows fc's, lenient, etc) in the brisbane area to approve 202,  supra 5 speed and vn diff/4 wheel discs. Contact details would be great, cheers

thanks ken i will check the hr arms. the tyres are 205/65/15. i know these are about 20mm bigger in diameter but it still would hit. they are the standard 40mm offset and they do sit in a fair bit - close to original i reckon.I have standard guards - not rolled. I am running hj brakes up front with vn rear. i just don't want to fork out for an adjustable one unless absolutely necessary. do you know the difference in piston sizes for both?? Thanks again

Hi guys i no this has been discussed numerous times and i have read thoroughly on the topic however just wanted to confirm things. I have mounted hq stubs and rotors on my fc (hr front, standard steering) and have redrilled them to commodore pattern. I have also already had a diff converted by pat gardener. With no springs and standard commy rims i have jacked up the front on full lock (using HKTG steering arms) and the wheel hits the guard about the point the bumpstop touches, however there is about 30mm more compression. Do you have to move the steering stops?? because at the moment to avoid hitting the guard i would have to move it about 50mm. Is this right? it seems like too much. Is it possible/legal to get bigger bump stops or weld a plate where bump stop hits. i put a 10mm peice of steel in where bump stop hits and it clears the guard. i know it will affect how much i can lower it but might be better than the steering option. Has everyone encounted this problem??

Also am wondering what proportioning valve for the brakes to use. i am running gemini booster with xb master. Any help on these topics would be great. thanks guys
