Okay, so my situation goes something like this. I have enough power in my car to sling it through the trap at 100mph but only with low 14sec passes. I am also tired of spinning my front inside tire at the autocross when exiting corners. I am seriously over this FWD bullshit!! I am beginning to really look for a late model GSX but I am not looking forward to putting my car back to stock and then transferring everything over to my new car. Not to mention my car has become a small legend here in little Melbourne FL. Because of that I am beginning to consider the possibility of purchasing a LSD. But I want to know will it really help me to hook up when I launch. I know my car could pull decent high 13sec passes if I could just get her to hook up. So let me know what you guys think you might do in my situation. If there is anyone out there who has driven a FWD with LSD and a GSX, let me know how they compare.

Later!!

Interesting dilema you got. I'd think that a quaife lsd would definetly get you 13s. You can always throw on slicks too and/or get one of those sequential mbc to keep low boost in 1st and 2nd. Even with a lsd you'll never have the traction of a AWD. on another note NO AWDs came with front LSDs.

They also don't need them! :D

Orange, you do have a tough decision to make. My advice would be to invest in some slicks, then an LSD if necessary. I'd save the buying-a-GSX idea for last. Don't get me wrong, you can't go wrong with AWD, but you might save some money and still be content with one of the other alternatives.

When they start pushing +350hp they start to. Adding a front LSD helps reduce power on understeer exiting corners too. More grip to the front tires.

Get an LSD. I know 2 guys that had GSTs put in an LSD and dropped their time at least 1 second. It was a 2nd gen GST run 13.0 at 110 on street tires. Not too bad.

I am personally going to go with a lsd too. I am deciding between Quaife and Cazz. I heard a lot of going things about the Cazz. Anyone have any ideas?

Quafie or KAAZ

The Quaife is gear operated where the Kaaz is clutch operated. The Quaife does not require break in where the Kaaz requires break in. If the Kaaz is not broken in right it will not perform good. Don't take my word for it, read it for yourself on their own web page!

The Kaaz is $200-$300 cheaper. Like all clutches, the Kaaz will eventually wear out.

My friend has one in his VR6 hybrid 86VW GTI. A pretty torquey engine in a light car. It seems to hook up really good off the line for him, but then again he never tried a clutch LSD so that doesn't really help much.

Hi Orange Crush, from what I have read the qualife LSD will give your car unique charateristics that is not like stock FWD or AWD. I think with LSD your car will feel like it's on rails, you can just give it gas out of a corner with minimal spinning.

I want one for my car if I have $1000 spare.

Thanx Guys!!

Thanks for all the great input. I am beginning to look at a LSD, a friend of mine has the exact same upgrades in his car and he is running 13.8 at 101mph, pretty nice setup. His 60fts are a lot better than mine.

But......another friend of mine here in our DSM chapter has two 95 GSX's so I am going over his house today to check them out. One of them is even orange exactly like my baby!!:D:D:D

I read here on another string somewhere that there is another company besides Kazz and Quaiffe that make a LSD for our car, anyone know who it is?

Yeah Phantom grips makes them. Although unlike the Kazz and Quaife it uses your exsisting diff. You actually replace parts in your current diff. The advantage is its like 200 bucks, plus install.

But LSD are definatly worth it. From what I have experience a FWD with good tires, and LSD can launch pretty hard.

Orange crush, the other LSD your thinking of is the Cusco. This one is also gear operated but I do not know much about it. The Phantom Grip is like an LSD but not exactly.

During normal operation a stock diff splits power between the front wheels 50/50. During slip power goes down the path of least resistance, the slippling wheel. This is where the term pegleg comes from because only one wheel is slipping.

The Phantom Grip is better because it locks the spider gears in your stock diff. With the Phantom Grip power is split 50/50 during normal operation and during slip. Power is put down 50/50 all the time.

A true LSD (i.e. Quaife) puts power down 50/50 during normal operation. During slip it transfers power to the wheel with traction. Say you launch and the right wheel looses traction, the LSD shifts torque to the left wheel. Say the left wheel looses traction and the right wheel regains traction. The LSD shifts torque back to the left wheel. When both wheels regain traction it goes back to 50/50.

A true LSD is better than the Phantom Grip due to this back and forth capability. The Phantom Grip is definetly better than stock because you'd have to spin out both wheels to totally loose traction whereas with stock you only have to spin out one wheel.

1. A Quaife is about $1100 at the cheapest.
2. The Phantom Grip is less than $300.
3. Switch to a GSX and start over again.
Its up to you. Getting a FWD to hook up is a challenge but doable.

99gst

Thanks for the explanation of the Phantom, I didn't know about that!!

I went and looked at the two GSX's yesterday. The orange one isn't in great condition, he really doesn't want to sell it to me, but the silver one is cherry. Looks almost brand new, has a 97-99 front end conversion, but it needs to be put back together, as the transmission and the motor are out cause he was gonna build it up. All I have to do is get him to put it back together and give me some numbers.

If not, looks like I will be shelling out the cash for a LSD.

This one was dug up from the dead, but it's good you're using the search. I don't think it would benefit GSX's that much, but I'm sure some of the higher HP applications it might, but I'm not an expert.

In doing your research, you should look into the different types too. There are clutch type, helical, full lock, etc... Decide what's best then choose a vendor with that type. They all have different torque transfer charachteristics.

My '03 Maxima 6 speed has a helical type from the factory. It's torque transfer is probably the most streetable of the bunch, but sometimes I notice I don't get 50/50 transfer to both tires.

probably the better the transfer, the less streetable the LSD, I'm assuming.

hey orange crush, have you done the window weld mod to your motor mounts, or gotten solid ones? I haven't myself but I've read about it making a world of difference. I agree with everyone about the quaife. As much as I wish my car was AWD, at this point I love my car and want to work with what it has. Get the LSD, get some motor mounts, get a good suspension setup (many people forget about that) and then some good rubber:D

I currently am running the BMTranny LSD insert and I love it. It's great @ launching compared to the stock LSD. Although my only best 60' is a 2.3(crap driver and crap tires) overall it feels like a better car while driving. I'd say invest in the BMT or for a little more the Phantom(although I've seen both and both are constructed VERY similiarly). That's are my 50 cents.
