Re: you want to change your 5X5 bolt pattern on 73-87 disc to 5X4.75

Hhmm.... The S-10 would be my first choice. I might have an S10 rear rotor in my possesion (I had a rear disc set-up for my G-body/pro-tour ride). What measurement would you need?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

If I remember correctly, The measurement is from the wheel contact surface to the back of the disc, basically furthest outside point to furthest inside point.
'94-'96 Impala - 2.335" (the brackets are specifically made to work with these but they have the 5x5 bolt pattern)
'89-'92 Camaro rear- 1.97"
'93-'97 Camaro rear- 1.81"
mid '90s S10 I think front - 2.87"
The calipers are from a '97 Camaro because they have the e-brake built in and, of course, work with the brackets.
I can probably use spacers to make some of these work, I'm just not sure how much spacing I want to do and how much is safe.

Ahhh.... The numbers may not mean anything then (because of the different calipers). The set-up I have is OE S10 (11" rotors IIRC) w/OE rear emergency brake.

I have everything minus one rotor that my buddy mis-placed some where along the line. I'll try & grab a rotor & put it inside a wheel & measure from the wheel 'pad' to the inside rotor surface (right?).

I just put the rotor hat down on the counter at the parts store and put a straight edge across the top. That is how I got the measurements and they are the same as stated in dimension info.

Re: you want to change your 5X5 bolt pattern on 73-87 disc to 5X4.75

Hola gents!

I've read over this thread a few times before joining this forum and am still somewhat confused on this topic. I have a 1984 1/2 ton Silverado. Will the 91 Camaro 1LE performance rotors fit my set up? It's currently a 5x5 and I am really trying to get it to a 5x4.75. Thanks.

Re: you want to change your 5X5 bolt pattern on 73-87 disc to 5X4.75

Also wanted to know if I could use these drop spindles with the 91 Camaro rotors.

http://www.ebay.com/itm/400140456280...84.m1423.l2649

The end result I am looking for is to safely get my 84 Silverado to a 4.5 inch pattern with about a 2" drop and that I can use with a 15" wheel. HELP!
