Big brake conversions

    I should be making some kits up at work for a bolt on big brake conversion

    Using 283mm discs on standard VTS/GTI calipers

    How much would this kit be worth:

    2 caliper brackets
    4 spacers
    4 bolts and washers
    1 pair of discs

    how much does it cost to make + labour then however much you want to make.

    Labour cost is not an issue tbh

    Dont want ask to much for them so just a rough price what they are worth

    How exactly would they work if you're using standard calipers?

    The standard caliper is moved out with the brackets and then bigger discs are used 283mm

    will the pad area still cover the disc though? as pad area is also a major factor in breaking performance as well as disc size.

    I'd have to check on that to be honest

    im sure it will as lots of conversions offer what your doing, but worth checking though as having the pad only covering 3/4 of the disc isnt really going to offer the full benefit

    Thats true yes i understand where your coming from. What size are standard VTS discs?

    the pad obviously wont cover the disc. it will be on the outer. the stooping is greatly increased though compared to standard.

    price would depend on discs. plain, grooved

    your prob looking at £40 quid for brackets and bolts, then discs on top

    so for you to sell. 110 a set for plain and 160 for grooved. or less upto you

    sounds about right from what i've seen on prices of other bits

    can you clarify for me?
    basically your moving the caliper out to create a higher leverage on the disc in essence
    that should give a greater stopping force as the caliper will be further from the rotational centre
    but i cant see how this will work fully as you wont be using part of the discs surface correct??
    i mean it will increase breaking force but there are better ways of doing it
    plus spacers and longer bolts on the calpier im not sure id trust as theres a lot of force involved in breaking
    and i know from a previouse job (running press tools) how easily an 8mm bolt will shear off
    if you can get good quality bolts then yea its a good idea but if your just using normal ones id rethink a little bit

    (not to put anyone off the idea like)

    What bolts would you recommend?

    I can get any type through work. high tensile?

    well high tensile are strong we used some heat treated stainless bolts
    cant really remember the grades ect

    but yea tensile might work

    just warning against like stanrad steel bolts really as they probably would snap

    no problem mate
    as i said its a good cheap way to improve the braking a bit

    but just make sure its done properly
    wouldnt want to hear that you did it and something failed resulting in the caliper coming off (worst case scenario lol im a pescemist)

    arent the bolts to hold the caliper on m12? High tensile 12.9 should be good enough i would of thought! i ran a kit like your doing on my r5 turbo, if you get the spacing right you can get almost all the brake pad on the disc, i think i had about 1mm not being used. Certainly improved braking. I'll be interested to see how you get on mate

    the caliper bolts are 12s yea
    just at my old work we used 8s more often so im mentaly scaling the forces

    i just didnt want him to put basic poo steel bolts in and then them shear off
    i think high tensiles would probly do the job as i did say on the other page (think i worded it as might though)

    just kinda trying to look out for him tbh
