Hubs sizes ?

I just bought some drilled and grooved discs and some 1.6 calipers off of Civic91,

now i want to know wether the discs will fit onto my 1.3 or will i have to change the hubs for them to fit?

They will fit as long as you have all the caliper mounting parts, but you will probably need a larger master cylinder to make up for the extra displacement of the caliper pistons (you will most likely end up with a low or soft pedal)

Are the Calipers and Discs from a 1.6-16V or a 1.6-VT?
the 16V ones will be fine but the VT ones won't fit without the knuckles.

they r off a 1.6 16v, all i bought was the calipers and discs nothing else, will they bolt straight on

they should fit, it will only take you about 1/2 an hr to test fit one side, without disconnecting brake lines etc..

ah right ok cool, cheerz m8 ;)
