alright c5 brake conversation is done and the different is night and day.

Nice.

Looks good, I'm going to be doing the swap over the winter I hope. I like the calipers without the Corvette lettering, where did you get the setup?

Are those 16" or 17" wheels? Doing mine this winter and wondering if I have to get new rims or not.

i got the brackets used calipers and ls1 spindles from SUTTERERMAN85 a member of ls1tech.com for a sweet *** price. i swapped the calipers at oreillys part#18-4703 and 18-4702 from a 2000 c5 vette. the rotors came from autoanything.com part#AR8260SR $73.00 a piece.

REVSON the wheels are the WS-6 17inch and you will need to bump up to thw 17inch for clearance.

how much did the conversion run you total?

around $600.00 needed to replace the tie rod ends and 1 wheel hub. the chassis has 212000 miles on it ball joints were good i was very suprized that the unbolt a nd came apart easy.

whats all included in a conversion? bigger calipers?

fbody and c5 calipers are the same dimensions, the fbody calipers are actually stronger. they have the ribs on top of the caliper for stiffness. alot of people over price c5 calipers, because most dont know that fbody calipers are the same. you can get the bracket to upgrade to c5 rotors while using fbody calipers. and it will cost less.

vettes brake alot harder than f body's do. im trying to figure out why. i thought it was better calipers but i guess not.

Aren't the pistons smaller on the Vette calipers? That alone would help increase pedal stiffness.

Or it could just be the way the pedal mounts or the size of the master cylinder. There are a lot of ways to increase pedal stiffness.

the calipers from the 2000 vette i used were ribbed as in the photo the rotors are bout an inch bigger than an fbody and has twin pistons were my original fbody calipers are single piston and actual smaller. as far as what was involved in parts, calipers, rotors, mounting bracket and ls1 spindle arm. i also installed stainless steel brake lines.

F-body calipers are NOT stronger. They DO have more clamping force than the C5 calipers but their somewhat weaker construction makes them more prone to caliper spread. So for normal driving, LS1 calipers will stop your f-body harder but will increase weight transfer/nosedive as a result. Corvettes stop harder because they are 100s of pounds lighter. C5 calipers will last longer and maintain your factory brake proportion and with the larger rotors, you will still get improved braking and MUCH longer rotor life/resistance to warping.

this may seem a dumb question then...but...wouldnt having larger rotors not make a difference unless you have bigger pads to compensate? otherwise its just the same pad area contacting the rotor, and the rest of the rotor is just in a sense, gone to waste?

cool. hey i tried looking for those rotors on that site you gave. i couldnt find them. You sure thats the right part #AR8260SR?? Could you put up a direct link?

alright. i guess i did look at that one. just the picture looked weird on the site. thanks! you just saved me lots of money!!

The better ability for a stock C5 to outbrake a stock 98-02 Gen F-body will have more to do with GVW, F/R weight distribution, shock valving, spring rates as well as a slightly front biased braking system usually equipped with better tyres and less to do with the rotor diameter and brake caliper. Bear in mind that this is more of the obvious differences, not necessarily all of them.

Believe it or not, a 4th Gen V8 F-body can come awfully close in performance, however it's not easily done with regards to a vehicle that meets "road worthy standards." Some areas to begin with will be improved shocks and springs, fresh brake fluid, good pads along with rotors with adequate mass mostly along it's width and less for it's diameter. Good tyres are a must. Along with those suggestions, ensuring a decent amount of weight is at least safely and effectively removed from the front end (even moving some to the rear, e.g. battery can help) will help a lot.

AFA the 93-97 F-bodies, the stock front brakes are way inadequate. C5 kit or at least a 98-02 F-body brake kit is about the minimum.

That's a good question and your idea is in the right direction, however it's not that simple.

For your example given, effective pad surface area is important with regards to "matching" it's rotor diameter, however the moment of inertia created by the larger rotor will still be present. What that means is that it will still affect front-end brake bias by increasing it, even if contstrianing the pads, piston sizes, caliper stiffness with it's respective hydraulics.

Generally, you do have the right idea concerning matching an appropriate pad size to rotor size since the pad surface area (as well as pad thickness and compound) is highly critical with the appropriate application. Inadequate pad material composition, and/or inadequate pad size and thickness will raise brake rotor temperatures quickly and unnecessarily.

What I should add for this thread is that it's much more helpful for the increase of mass of the rotor to be placed along its width between the friction area and the outer sides of the ventilated area (essentially thickened rotor 'cheeks') as well as properly sized and located vanes. This ensures that there is a thick enough area for effective heat transfer properties whilst not affecting too much of the MOI.
