This is an interesting topic and I would definitely be interested in saving about 30lbs of unsprung weight. I recently bought new lighter disks and wondered if my now spare disks would would bolt onto the axles. It turns out they are fairly close and it would be easy enough to make a bracket. However a quick search showed that I could just buy some from Wilwood at a reasonable price and then just make a bracket for the caliper. My Wilwood brake pads are held in with a split pin so it would actually be quicker to change the pads by removing the back (boot/trunk/panel) rather then remove 2 wheels. http://www.wilwood.com/Rotors/RotorList1.aspx Talk about saving weight for about $500 I could get a 3lbs per side disks and calipers which would be a 20lbs reduction. Obviously not good for anything other than autocross of drag racing though. Attachment: IMG_20170206_202212.jpg Attachment: IMG_20170206_202645.jpg

And then there's the heat transfer to the diff and seals . . . . |

They are Wilwood units. Discs 1.6lbs part no 160-3411 Caliper - 2 pistons 0.9lbs part no.120-12178 Caliper - 4 pistons 1.7lbs part no. 120-10714/5 They have lots of light options depending on your requirements. The parts really are great quality, customizable and rebuildable. The difficulty is getting them mounted on the car. |

Thanks. Actually the rotors may not be up to it; they say "Performance Characteristics Unsafe for street use & unsuitable for most forms of Racing. Special racing application only. IE. Dirt Sprint & Midget. Can result in catastrophic failure when misused." Also looks like the GP320 calipers need .75" thick minimum. But there are plentiful superbike calipers on ebay, though they may not be quite so light. These rotors for Harleys ought to be good enough, but pricey. http://www.ebay.com/itm/301588391763?_t ...

Damn $650 for just the rotors. If you look through the Wilwood site they have plenty of different calipers and disks depending on your needs. My current front setup is the Forged Dynalite calipers and some thin drill disks. But I previously have vented. The Vented came in at around 11lbs with disk and caliper and will be more then enough for anything a 1000lbs trike can throw at them. I am not affiliated with Wilwood in any way, I feel like a sales rep. Just a happy customer as they are a great product. |
