I see they have the 5 lug setup and I found one nearby for 500 with body damage, I might buy it for the lugs and brake swap, maybe even LSD.

Is that LSD even good or should i go with the FD or minata one?

Whats the braking setup on the GXL?

Is that a good deal for the parts to convert to 5 lug?

 

The GXL has the same brake setup as the t2, 4 piston racing brakes in front, 2 piston brakes in the back.

Only the s4s (86-88) are guaranteed to have an lsd - and it's a clutch one so it's likely worn by now. A clutch lsd is often better for real life driving traction situations, ie: snow, ice, water - and it's much better than a viscous one.

5 lug in itself isn't going to do much, and unless you're auto crossing or track racing the brakes aren't mandatory.

Ps. you have 90+ posts, I feel like you should know to search for the easily available information (and it's mostly in the main 2nd gen sticky)

 

I checked the FAQ I didn't see anything about the brakes in there and I was actually searching while waiting for a response =/ , Thank you though, I think im going to scrape change to buy the car.

 

The rears have single piston.

Also, the S4's aren't "guaranteed" to have an LSD.
Only the following USA model 2nd gen RX-7s had a LSD from the factory:
86-88 GXL
87-91 T2
88 GTU
89-90 GTUs (however not the 89-90 GTU)

You're just full of all kinds of fun information.

 

When it comes down to it, for real world applications, it's debatable whether the Torsen or the clutch type is better. I prefer the torsen.

In racing situations, the Torsen is better than the clutch-type, due to it's progressive lockup characteristics. The weakness of the torsen is that if one wheel becomes airborne, the Torsen exhibits no limited slip characteristics.

In drag racing situations, the clutch-type is better since it's stronger (durable) and the initial lockup is also stronger.

I vote we chuck all the VLSD's and get some decent ones in the rearend. I got my Torsen waiting to be installed.

 

Sorry if i'm thread jacking but I was just wondering if there is a way that I could find out if my lsd is worn out without having to open it up?

 

mmm....is it locking up the wheels? What kind of car do you have?

 

i have lsd and mine is a s5 1990 gxl coupe to so ya

 

s5 gxl's don't come with lsd's from the factory. It says so in the mazda brochures posted at the top of this section. If you have one, it's most likely aftermarket or GTUs/Miata swap.

 

he's right, the rears do have single - I don't know where that bit of misinformation worked its way in - i might be mistaken, but maybe it's the 944 rear brakes are 2 piston racing style (clip in pad, floating caliper)

And the 4 pistons and guaranteed lsd was only applicable to s4 GXL as I didn't realize we were talking about anything else.

Also, in your search, the factory spec page lists the brake setups.

at an experienced user TRYING to insult an answer when there was one tiny bit of misinformation

 

I think it is locking up the wheels, sometimes when I try to turn onto a street quickly from a stop the wheels lock and click sorta. I have an 86 gxl.

 

k, yours should have the lsd, try the wheel test I guess. Jack up both rear wheels and rotate one wheel. The other wheel should rotate the same way. There's other LSD tests but i dunno if they'll tell you how worn it is.

 

alright thanks!

 

im pretty sure open diffs will spin both wheels freely too ^^ at least on my 240 it did.

truthfully, the best way to find out is to jack up the car and look for "LSD" or "Limted slip differential" stamped on the diff. i forget what exactly it says but mine says Mazda limited slip or something on it.

 

if you have an open diff and rotate one wheel, the other wheel will rotate in the other direction.
