I bought a set of 2wd blazer spindles and hubs, in hopes of doing the c5 front brakes since I already have a set of calipers. Unfortunately my TT2's dont have enough clearance for them, so I need to do the smaller ls1 brake setup with the stock spindles. The good news is I can use my calipers with the ls1 setup but now I have wasted $ on the blazer spindles. I will let them go for what I paid for them ($100) plus actual shipping.

Has any one else done the ls1 swap from fly n bye and recommend the needed parts? Have you used the c5/c6 calipers instead of the ls1 calipers? supposedly they interchange while using the ls1 PAB.

I went with Kore3 for the hubs. Little more expensive than using cut down rotors, but really well made and will probably last longer than the car.

For brackets for the LS1 swap I emailed Stephen Leach from one of the S10 boards: leacher05@yahoo.com

His brackets were $30 shipped (Back in 2012, so the price may have gone up), were mailed out quickly, and fix perfectly.

From what I know of flynbye you'll pay more and Ed will take forever to ship them.


And yes, you're correct about the C5 calipers working with the LS1 abutment brackets.

Thanks Dave.

Do you remember how much those hubs were? I cant find them on their website. I will send that guy an email on the Brackets, Thanks!

I was thinking about cutting my rotors down into hubs and installing longer wheel studs since they are brand new.

I have the calipers off my ls2's donor car, 2006 gto. They are actually the same as c6 calipers. Trying to get this done as cheap as possible.

Thank you for the heads up. I was looking at buying a set of his hubs and brackets but I don't have that kind of patience. I'm going g to see what it will cost me tomorrow to have my rotors cut down and longer studs pressed in.

I managed to actually get ahold of Ed himself after his wife was a real xxxx to me on the phone. She would have rather gave my money back than complete a sales transaction.

Total polar opposites, those two. He was very nice and understanding, her, well we can't post that particular word here.

But the parts are nice.

If I had known on the suppliers SS Ninja posted above, I would have gone with them.

Get good bearings. As for rotors and pads, this is who I went with. They're COMPLETELY cast and manufactured in Canada.

MaxAutoPart

Very nice pieces.

Big brake woes... No pun intended, right?

I sent an email to the guy that dave referred me to, and I'm going to look at cutting my rotors into hubs tomorrow. Does any one other then flynbye sell reasonable hubs? I dont really want to spend $200-$300 just on hubs.

Those rotors you posted are probably what I would buy. Nice price and comes with pads.

I came across this:

http://www.bigbrakeupgrade.com/ls1_parts.html

I do not know if the rotors for a third gen F body are the same as a g body, in the hub part anyway. But these are $125.00.

Another reason I liked the FlynBye hubs and the ones listed above I suppose, is for the 1/2 inch studs. Now on my car they are all the same. (1/2 inch rear too)

Do you know how much longer the studs need to be, or an overall length? whats the stock size, 7/16"?

Bit late in my response, but I should have mentioned that the Kore3 hubs are a bit expensive. That said, most of the vendors are charging almost that much for a glorified cut down rotor. At that point you're better off buying a cheap set of rotors and doing it yourself.

The hubs from the bigbrakeupgrade site look to be another variation on the cut down rotor, hence "cut from new castings". smile

Factory studs are metric. According to thirdgen.org, Dorman part 610-323 is what you need.

Thanks Joe.

Like I said, I emailed the guy that Dave got his brackets from, but is there any one else other then fly n bye that makes these brackets?

I'm not sure. There has to be. I thought about producing them myself, but my engine/head building is about to start for the year.

Cutting the rotors down on stock hubs leaves them fairly weak and prone to cracking. The old style hub/rotor casting combos were designed so that the cast in rotor reinforces the hub casting. The combined hub/rotors were very strong but a pita, to repair, mill the rotor off and the casting is weakened. Seems like all the g body brake upgrades have shortcomings. The Kore3, hubs while expensive are much safer than milling rotors.

Meh, I dont think strength will be an issue. Seems to be ALOT of people running them and I haven't heard of any failures.

Jason, don't mess around with safety...especially when it comes to brakes. I'd rather run a smaller system that you KNOW works and is safe than scab together something else just to run a larger rotor. I'm not saying the cut down hubs are unsafe, hell I thought about going that route myself. I just know that you shouldn't scrimp when it comes to safety items.

BTW, I can lock up my sticky 275s up front with my 10.5" rotors and metric calipers... How much more brake do you need? laugh

Daves guy got back with me, $40 for the brackets and bolts. Tough to beat that!

Lance,

I really have a hard time seeing how the machined hub can be unsafe? Has any one reported any failures with them?

I can also lock up my stock brakes, especially with the hydro boost. The c6 calipers are lighter, and look better and will be a cheap mod for me since I already have them.

Turbo Buick guys complain about milled hubs developing cracks by the studs.

I read about the hubs cracking when pressing in studs after being cut down, but never of a failure even being run with these cracks.

I plan on changing studs before cutting them down.

I thought about cutting my rotors down too. But with the cost of the studs I wanted, drilling and tapping, I think it was better to get the hubs.

Get the hubs. You won't regret it. Everybody's doing it. You want to be cool, don't you? Peer pressure!
