Ok I have an 85 trans am, recently painted and bought new 15" wheels, well i wish i went bigger but its too late....

Right now i have disc up front and drum in the back. My first question is how big are my stock disc breaks in the front? I would like bigger disc breaks all the way around, i read that the c4 kit will fit? Anyone know an approx price? And the wheels are Eagle Alloy 028 series...

 

You can run stock 4th gen LS1 style brakes if you use spacers and grind some material off the calipers.

Thats the biggest brake upgrade i can think of that will fit 15" rims.

 

Front: 10.5"

Your 15"s will pretty much limit you to 12" C4s or 12" 1LEs. Price will vary on if you can supply any of the parts yourself or if you buy a full kit ready to go. LMK if you need any help with this, I have all parts on hand.

ya i'd have to buy it, probably the c4 kit, it seems like your the go to brake guy, around how much would a c4 kit with everything i need be?

ebmiller?

I sent you a PM a few hours ago..did you check it?

Ed

 

ya sorry, usually it notifies me when i have a PM

 

i was thinking wouldnt it be cheaper to just get a 4th gen rear w/ the ls1 disc brakes?

 

I'm pretty sure the LS1s wont' fit the 15" rear wheels without some grinding of the caliper which I don't recommend at all.

ohhh, i think i meant was the lt1 ones? would those clear?
thanks

 

those or another thirdgen rear w/ disc? cant really afford the kits right now...

 

Brakes from a '89-97 will work as they all install practically the same.

way OT but I used to head up to Bills auto parts in Tolland all the time. I'm from the area but live in DC now. Cheers

 

haha cool, ya ive been there a bunch of times
thanks for the info EB

 

I'll be in Hamden tomorrow to visit yous guys.

Ed

 

haha cool, so from 89-97 the rear disc will fit and not rub w/ 15's?
thanks

 

That is correct.
