So, I searched and came up empty...
I was wondering if 90 Prelude SI rear disk brakes can me switched over to
my 90 Civic Si? If anyone knows please fill me in..
And if i need anything extra for the conversion?

thanks!

 

1990 prelude discs are 114.3mm, so unless you wanted different lug patterns if they even fit...

 

You sure about that? I thought 91 and older were 4 x 100 but I could be wrong, maybe someone with a prelude will chime in.

 

i had prelude wheels on an accord, but i didnt check the year. you are probably right now that i think about it. i had wheels off a 92

 

Nah they are the same. I put some wheels from my civic onto the prelude before..
