DAT Inter Posted January 6, 2009 Share Posted January 6, 2009 Hey there peeps. I was wondering if anyone had done or know if it possible to shave of a minimum of 8mm in total from both sides (as in 4mm one side x2) from front UK brake calipers?

JustGav Posted January 6, 2009 Share Posted January 6, 2009 *cough* WHAT!!! You want to remove material from the calipers, there are a few reasons you shouldn't EVEN consider this. Quote Link to comment Share on other sites More sharing options...
Thorin Posted January 6, 2009 Share Posted January 6, 2009 Why? Bought the wrong offset wheels perhaps? Surely spacers would be better. Quote Link to comment Share on other sites More sharing options...

DAT Inter Posted January 6, 2009 Author Share Posted January 6, 2009 We do it on rally cars all the time and never have any bother wilth them. Anyone done it? Quote Link to comment Share on other sites More sharing options...

This isn't the first time you have asked for opinions on threads and then just answered back with 'We do it all the time'... obviously you have the experience, so just get on with it then!. http://www.mkivsupra.net/vbb/showpost.php?p=2222453&postcount=9 Quote Link to comment Share on other sites More sharing options...
DAT Inter Posted January 6, 2009 Author Share Posted January 6, 2009 We shave calipers on rally cars so as to give them the ability to fit snow tyres for certain stages. I was just wondering if anyone had done it before on the UK supra calipers before just incase there is like a fluid well close to on of the walls. Are the UK calipers cast as well?

Ark Posted January 6, 2009 Share Posted January 6, 2009 I recall it being done by TDI Ltd several years back, to fit some Blitz rims that'd been bought to the wrong offset. No idea how much was shaved, or whether the lucky owner subsequently crashed in a wrecked-brake-fireball-horror. I certainly wouldn't want anything to do with it.

Tricky-Ricky Posted January 6, 2009 Share Posted January 6, 2009 I guess it could be done, but i wouldn't even consider it without first dismantling them and checking with a micrometer just how much metal is there, surly that what is done before removing the material from the rally cars callipers?? if not then all i have to say is "cowboys" Quote Link to comment Share on other sites More sharing options...
Thorin Posted January 6, 2009 Share Posted January 6, 2009 Surely proper rally teams just have wheels that fit properly? Quote Link to comment Share on other sites More sharing options...
DAT Inter Posted January 6, 2009 Author Share Posted January 6, 2009 Surely proper rally teams just have wheels that fit properly? Amazingly its very difficult. Its when you hit a stage and then you have to fit snow cutters on d you have no clearance. Some teams just run bolt on spacers others have pre shaved calipers.

Terminator Posted January 6, 2009 Share Posted January 6, 2009 I would have thought given the possible fatal consequences if of skimming calipers, rally teams that do it, know the exact dimensions of calipers both inside and out. I have seen 1mm or 2 mm shaved off 300ZX calipers on corners and edges and they were fine for years. You are considering 4mm off each side, this sounds far too much. If the calipers could run 8mm narrower Toyota would have done it when designing the car, as weight reduction was a huge priority for them. Go for the lesser of two evils run spacers.

Matt H Posted January 6, 2009 Share Posted January 6, 2009 4mm, that does seem a lot considering. I'm sure a spacer would be the ideal solution in this case. Quote Link to comment Share on other sites More sharing options...
gaz1 Posted January 6, 2009 Share Posted January 6, 2009 4mm, that does seem a lot considering. I'm sure a spacer would be the ideal solution in this case. and i have a pair of 3ft spacers going spare now i have my new wheels Quote Link to comment Share on other sites More sharing options...
couv3z Posted January 6, 2009 Share Posted January 6, 2009 sell me your uk spec brakes and you can fit my smaller j-spec's Quote Link to comment Share on other sites More sharing options...
Matt H Posted January 6, 2009 Share Posted January 6, 2009 haha, But i never had any spacers with the old wheels in the end Quote Link to comment Share on other sites More sharing options...

Branners Posted January 6, 2009 Share Posted January 6, 2009 Just so that when this thread comes up in the searches... The answer is NO, that is not an advisable way to make wheels fit. Neither is it good to shave the spokes on the wheel either (which I have seen done). If you plan on doing this mod please let me know so I can ensure you arent in any of the convoys I organise. It might be an idea to do a search for news stories about that guy with a Land Rover that bodged his brakes. Killed his kids and is now in jail.

RobSheffield Posted January 6, 2009 Share Posted January 6, 2009 Does he need to be an engineer to state that its a pretty dumb idea? If Toyota went to such lengths to make the car light, would they put any more thickness in the caliper walls than necessary? And you want to remove some so you can fit blingy wheels? Just buy decent wheels! Quote Link to comment Share on other sites More sharing options...
gaz1 Posted January 6, 2009 Share Posted January 6, 2009 as with most things designers allow anything around 33% safety margin, so if the caliper walls are 10mm thick which i doubt, and you shave 3.3mm off then you have no safety margin, people do not design things for nothing leave well alone;) Quote Link to comment Share on other sites More sharing options...
DAT Inter Posted January 6, 2009 Author Share Posted January 6, 2009 How can anyone give an opinion on this who does not look at it from an engineering perspective? I have no experience with... lets say Yokohama tyres. So how could i give an opinion on them when asked knowing nothing about it. Quote Link to comment Share on other sites More sharing options...
