Since you already have the LS1 upgrade, you have what you need.


All I was saying was; if you had a stock LT1 setup, you have to get LS1 spindles for the LS1 brake upgrade.


Your car already has that upgrade; someone else has already done it, nothing for you to buy.

First let me say I have converted my car to run LS1 brakes both front and rear so I am VERY well aware of the differences between both setups. I am not trying to make you look stupid or anything, I just hate misinformation.

No, but you did say:

You have to change the axles for the same reason you have to change the spindles on the front.
This is not correct. You have to change the spindles up front because there is no way the larger LS1 rotor will clear the LT1 spindles. Also the mounting holes for the caliper are different. On the rear you have to change the axles because the LT1 axles are too long. So the reasons are not the same.


Also, the parking brake IS different on the two setups. I did misspeak when I said it was independent of the rotors, it's not. However, it is different on an LS1, the parking brake is actually on the inside of the rear rotor; the only point is, it's different.
Correct, although I would argue the LS1 parking brake setup is much better, not just different.

The biggest thing I was driving at is that it's not worth it to try and upgrade the rear, just leave it alone; get better rotors and pads. However, the front upgrade is worth it, but you do have to get different spindles for the LS1 setup.
Yeah, the rear's probably aren't worth it but I did it anyways Mostly because I have a serious dislike of the overly complicated parking brake system the LT1 brakes use.

You are thinking about this too much. If you have LS1 brakes now, then you will need LS1 parts if you break something (i.e. a spindle). If you have LT1 brakes then you will need LT1 parts.

As I said a few other times. The entire point to this whole thing is that the systems are different; that's it. The fact that I said "you have to change the axles for the same reason you have to chang the spindles" was simply ment that they are both unique to the LS1 system. If you read more into it, sorry, but that's all I was trying to say.

Also, I never said the two rear setups were better or worse in any way, just said that they are different; I'm glad you like yours.

Quit trying to read more into this than it really is.

All I'm saying is that it's different, nobody can argue that.

By the way, I've converted mine also; your not the only one.

Let's end this thread here, this is rediculous.


Peace

just for the record ...

... if you want to use your LT1 steering knuckle (spindle), you can modify it, use the adapter brackets that are available and mount the C5/Z06 brakes. I have heard that you can mount LS1 brakes, but don't know those specific details.

I can see using the LS1 setup, because you can run 16" wheels, but if you already have 17's, then do the Z06 setup.

Yeah, your right. I had 16s and wanted to keep the factory look. If I had 17s, I probably would have gone with the C5 or similar setup.

Can't use the LT1 Spindles to mount the LS1 calipers and disks.

Get the entire LS1 setup if you're intent on keeping 16 inch wheels. It is very inexpensive to obtain the entire package: spindle, calipers, disks, hoses, ABS plugs and even hubs. I did my daughter's '95 TA for about $170.

Here's an Ebay example. If he doesn't currently have any on auction, call or email him to ask. Kerry is very accomodating.

just looked up the part numbers for the spindle/hub assembly for an ls1 t/a and an lt1 t/a and they are the same part number
for the ls1 brake upgrade
1. you must use the ls1 steering knuckle
2. must use the ls1 caliper and mounting bracket
3. you can use the lt1 lines but must use the ls1 banjo nut
be sure to bend the mounting braket on the frame as not to stretch your lines
4. you may use the lt1 spindle/hub assembly for the swap they are the same part
5. make sure the bleeder valve on the calipers is positioned in the up position the calipers are reversable.
that should sum it all up for ya and these are the facts
and it will fit with 16 inch wheels there willl be about 8 mm of space between the wheel and the caliper....have a nice day

oh and just for terminology sake the spindle is the part the wheel mounts to and the hub is what the spindle goes into and the steering knuckle is what the hub and the spindle mount to with 4 13 mm bolts also the spindle/hub are a sealed unit

For the record, the wheel bearing assembly (hub) is mounted with four 10mm bolts, not 13mm.
