Martins Stag Posted November 23, 2013 Share Posted November 23, 2013 I've notice on EBAY that MGF have some nice looking Alloy 4 pot brake callipers. Does anyone know if they are the same bolt pattern to either Spitfire or GT6 callipers? I assume someone has looked into them as an option to upgrade the brakes?Martin Quote Link to comment Share on other sites More sharing options...
esxefi Posted November 24, 2013 Share Posted November 24, 2013 I have a pair in my garage which I bought some years back and never used them.For a spit they are overkill and they are not particularly lightweight anyway compared to other after market stuff like wilwood or hi spec,but they are made by AP so would be reliable and pads should be easy to obtain.I don't think the bolt spacing is a direct fitment so would need some machining of calliper or an adapter made,and you would need to fit vented discs as that is what they normally run with. :) Quote Link to comment Share on other sites More sharing options...
Deleted User Posted November 24, 2013 Share Posted November 24, 2013 Vented discs are readily available for the Spitfire/GT6. Has anyone tried this conversion? Quote Link to comment Share on other sites More sharing options...
Martins Stag Posted November 24, 2013 Author Share Posted November 24, 2013 I have Capri ventilated disks with space standard callipers But I am reluctant to pay out expensive callipers! I think they may be overkill but they will reduce the unsprung weight?Martin Quote Link to comment Share on other sites More sharing options...
uksnatcher Posted November 25, 2013 Share Posted November 25, 2013 I would say the caliper is too wide, for a reasonable conversion.MGF use 16"+ alloy wheels with these calipers, the std 15" wheels foul the upgraded caliper, look how far into the wheel they go.I know they are using the larger MGF disc which will throw things a bit, and are way to big for the spit and look like they sit further inboard than the Capri/Saxo/Montego discs too.Heres some pics of them and fitted to an MGF with 16" wheels.These look BIG calipers and doubt they would fit, will need a lot of thinking about and engineering to make them fit the Spit with Triumph wheels (standard or after market) or MGF wheels and Capri/Saxo/Montego discs, probably need a huge hub spacer to bring wheels out enough to clear the calipers, kinda defeating the object of reducing unsprung weight.

Deleted User Posted November 25, 2013 Share Posted November 25, 2013 they do look a little BIG! would be interesting to see if they bolt on or how close they are Quote Link to comment Share on other sites More sharing options...
uksnatcher Posted November 25, 2013 Share Posted November 25, 2013 The MGF alloy caliper is a Rebranded AP Racing product.MG part number is CP7601 from the AP 7600 range.Here are the specs if anybody likes doing the sums... ;)http://www.apracing.com/product_details/road_car_upgrades/road_brake_calipers/4_piston_calipers/cp7600_family-130mm_mounting_centres-suits_%c3%b8295x24mm_disc.aspx130mm between locating bolt holes (5.1")........... so no, it wont just bolt on.STANDARD CALIPER BOLT HOLE DISTANCEType 12/14 caliper (Spitfire) bolt distance 3.25" (82.5mm)Type 16 caliper (GT6) bolt distance 3.5" (89mm) Quote Link to comment Share on other sites More sharing options...
GT6 M Posted November 25, 2013 Share Posted November 25, 2013 they fora 305 mm disc, same size as I run.so unless ye got 15 inch wheels or bigger, then its a nogo.And also depends if the calipers are ok with the triumphs off set for the disc, 27 mm BUTT, owt can fit with a bit of work, !!!!M Quote Link to comment Share on other sites More sharing options...

uksnatcher Posted November 28, 2013 Share Posted November 28, 2013 Spitfire bolt holes are 82.5mm, Gt6 are 89mm, MGF are 80mm Rob.Some fiddling with the holes are needed mate.... ;) Quote Link to comment Share on other sites More sharing options...

Nick Jones Posted November 28, 2013 Share Posted November 28, 2013 Nice caliper....... but:Too big to fit under 13", 14" and possibly 15" wheels. Wrong bolt spacing and has threads (helicoils by the looks) in the holes when you need through holes.Clearly a perfect conversion candidate......not.back to fiddling with holes.....Nick Quote Link to comment Share on other sites More sharing options...
