    Hi all, I have done a lot of searching, and I cant seem to find a good source of this information.

    What are the largest calipers that will bolt directly on to the ST162 GTS Hubs and still fit under the GTS wheels?

    Also, what are the largest that bolt right up, but require larger inside diameter wheels?

    Thanks

    st185 brakes but maybe you'll need 15" or 16" or st205 with bigger wheels anyways.

    So, the bolt spacing behind the hub will accommodate the 185 and the 205 caliper brackets without any issues?

    Excellent!

    I am needing to upgrade the front brakes. The rears right now are barely getting used. Over a 14 hour race we went through about half of our front pads and less than 10% of the rears. Additionally the rear pads bite really hard and can sometimes cause issues when diving into a corner.

    Does anybody have the specs on the fronts of the 185 and 205s? I would like to know the size of pad and rotor they work with as well as the inside wheel diameter required.

    Thanks!

    No definitely not.

    205 calipers require various spacers, grinding and machining of the rotors.

    Imho not a very neat upgrade and will set you back about 1k once you factor in buying decent rotors and pads etc.

    Series2 st18x is the easiest no fuss upgrade.

    Or get the small 4pot ceika kit.

    I've got the series 2 5th-gen front calipers, are the 5th-gen rear calipers bigger than the 4th-gens as well?

    I have ST185 front brakes (single pot) and they can be fitted without any modifications (caliper & disc). Disc size is 277mm, and you'll have to use 15" rims.

    ST205 fronts are quite rare to find, needs modification and 16" rims to fit, and expensive, especially to race it and have discs and pads replaced regularly.
