Yup, going to start gutting it for parts to use on the base. I'm taking the 5 lugs, brakes, and wheels from the GXL and swapping them onto the base. Anything else I should take from the GXL and put on the base? Struts / springs?

 

Series 4? If so, the limited slip rear-end

 

What's different about that compared to the posi that my base already has?

 

ok ive been wondering... is there a difference between LSD and posi trac rear end?

 

That depends, if you auto-X the LSD will be a night and day difference from the posi.

 

ok.....well, whats the DIFFERENCE?

 

Limited slip only allows the wheel that's spinning to do that for a short while before it locks the two sides together and transmits power to both wheels. Upside-none of that inside tire smoking like crazy when you turn a corner on the gas.

I don't believe the base has LSD.

If you want, you can swap the springs & swaybars but I'd only do that if you're getting new struts. no sense doing that work and swaping the old struts over, they're um...old.

 

Posi (positive traction) is basically just GMs term for a limited slip. I belive ford uses (traction lock). Various companies use different terms. Its all basically the same thing. Basically it wont let just the one wheel spin, it will lock up both for better traction.

 

Exactly, it's all a bunch of term's used to describe the same thing, posi is the same thing as a limited slip, and no, base did NOT come with a limited slip.

 

Funny, my base has both tires spin on a hard launch.....

 

That is because the skinny base model tires do not provide enough traction. They will both spin very easily. If you upgrade the wheels/tires to something significantly more grippy, you will not be spinning both wheels anymore.

 

Hmmm, so I guess I'll just take the LSD from the GXL also.. That way I'll be sure I'll spin both wheels when I put the new wheels with some better tires on.. Is the rear sway worth getting - or is there a rear sway bar?

 

Yes, Id say swap both the front and rear anti-sway bars, they are both a bit beefier on the GXL.

 

That's what I heard, just wasn't sure if it had a rear sway bar stock, and if it did if the GXL's would also be a bit beefier..

 

Looking at your webpage...is it just me or does your "Donar" car look much nicer than your "project"

 

The engine is siezed, the interior is gutted up, it needs a new driver door, needs to be rewired on the inside, needs a lot of work. So I decided to just keep the lighter model and take parts I need from the GXL

 

ok, so jdubs99 why would there be a night and day diff from posi to lsd if they are the same thing?

 

I think he is just confused with that statement.

 

I recommend dropping the whole unit as a whole and swap it out. Better than doing it individually and much quicker too.

 

oh ya i think the GXL has beefier suspension than the base too (never worked on a base, but it sounds like the GXL would have better springs and struts)

 

Don't forget the speedo gear,You'll need to change it because you are going to a larger wheel size!

 

I just did this and here are a few things I learned:

1. Drop the whole rear sub-frame, once you disconnect the shocks & get the LSD unbolted from the driveshaft its only four bolts to drop it.

2. ANTI- sway bars are beefier, and are a good and easy swap, that is if your car doesnt already have an aftermarket bar(s)

3. It would be good to invest in some new PE anti-swaybar bushings while your at it, my rubber ones were pretty worn and I would have loved to have some PE ones at the time.

4. Its worth the effort, so far my car is alot more predictable and stable. That and I can get some decent tires with a more popular tire size.

 

Wheel size has nothing to do with the speedo being on or off..

It has to do with the tire diameter. If the tires are too big, it'll read wrong, and if the tires are too small it'll read wrong.. You componsate.

The 15's and 14's didn't use a diffferent diameter, but just a different wheel / tire combo.

 

The wheel/tire combo on the 15s is larger in diameter compared to the wheel/tire combo on the 14s, but just slightly.
