Pro Touring Big Brake Spindle/Knuckle Question

[Robert]

Hi,

i want to buy a big brake kit for my GP, ive disscused with Rick from Bear-Braking over a 14" rotor-6 piston for rear/front complete w/ spindles. He qoutes me an kit with a oe style drop spindle 2", so im not shure whats the best way of spindle for my project.
B-body spindle with global west uppers/lowers w/ tall balljoints or a the g-body drop spindles with tubular uppers/lowers, what i the difference between G-/B-Body on the street, or is it only for rotor clearance ?

Kore3-Tobin told me the best way for my pro-touring project is a AFX Spindles, but thats crazy money for it...have somebody experience with AFX???

9.5 x 22" wheels all around...

Thanks

Robert

Hello anybody there ???

I'm no expert and somebody will have to back me up on this but here goes: A relatively easy and cheap way to add bigger brakes is to swap the stock g-body spindles for those from a b-body so you can use (3rd gen?) camaro front brakes which are inherently larger like 11.5" or so. An additional benefit was that you could gain positive caster which creates negative camber while turning and improves handling without creating uneven tire wear. You'll have to look into it but pretty sure the b-body spindle will slightly affect ride height by .5" (not sure if this is higher or lower) this may be a better option than g-body type spindle with 2" drop and your 22's...but depends on what you want and what fits of course. Then also using the b-body spindle requires the use of specific tubular upper control arms (and/or tall upper ball joints?) from the aftermarket like the global west pieces that you mentioned. The last time I looked into this there was somewhere online that explained the requirements for adapting the b-body front spindles and camaro rotors....either way there is a difference in the 2 spindles and like everything, it depends on a lot of variables and what you're looking for in the total package.

I have never done the spindle swap so I know only what I have read. The problem with the B body spindle is that is hurts ackerman angle and increases bump steer when used on a G-body. It also changes track width, and therefore wheel backspace requirements, which can be good or bad depending on what wheels you have. SC & C does a very good job of explaining this: http://scandc.com/new/faq#n627.

That being said, lots of people have done the swap and are happy with it, which allows them to run bigger brakes using stock GM parts. Another option that is getting popular is to use spindles and brakes off of certain 98 and newer S-10 trucks. The spindle is a bolt-on and allows use of the bigger brakes on some S-10s. You'll have to search this and other G-body forums to get more info on that one.

If you are buying aftermarket brakes that work with a stock dropped spindle, then I see no advantage to using the B-body spindles. By going with aftermarket brakes, you're eliminating the primary reason for using the B spindles, which is bigger brakes on a budget.

the 12" rotor with the B body spindles use the same caliper and brake pad as the 11" rotor with the f body spindles.

why not just modify the stock g-body spindle for the LS1 Camaro 12" discs/calipers or what i did and modify it for 13" C5 Corvette calipers and rotors.

The AFX spindles are not cheap but worth the money,They are light weight and can run any c5 or c6 corvette brakes out there.Here's 3 brake kits http://www.kore3.com/products.php?cat=11 all oem corvette parts makes replacements later on easier.

The question is makes it sense to ride a 14" rotors on a stock spindle or isnt good for the driveability?
