I know THere is the SLD from peloquin for 800$, but someone mentioned there
was a "MIni-SLD" kit ?

I tried looking for it and could not really get any information on it.
anyone have a web site adress where they explain/sell this part, I do
realize it is not (by far) as good as a quaife, but I don't have 800$ at
this present time to spend on the tranny I am about to rebuilt.

thank you

The Peloquin mini-LSD kit IS the Peloquin Pelolok 80% LSD kit, A.K.A. the Velocity kit.

Gary Peloquin described 
customers' reactions to the Stage II Diff Upgrade
this way: "The first reaction is that people really 
notice the difference in the steering responce under 
power. The car steers tighter - on the throttle the 
car goes toward the apex. The guys who live in the 
snow and the ice really love the added winter traction".
If those descriptions sound to you like the way people
describe the action of the high-priced Torsional differen-
tail, you're on the right track. Make no mistake, this 
under $100 easy to install product is no substitute for 
a $1,000-plus Torsional instalation. However, it's a great 
alternitive for the person on a limited budget or the 
racer in classes that do not allow a full-on limited slip 
or special differentail.
The original pre-load differentail was introduced with 
the second year GTI, back in 1983 on the 1984 models. 
New, it felt like a limited slip on the rack, but one 
turn by hand and it was clear that the two or three pounds
of preload it offered was of little or no value as a limited 
slip. It was probably added by the factory to
reduce vibration, but that didn't stop the less-scrupulous
tuners from touting it as a limited slip, even in stock
form ! This upgrade isn't something new, either. Peloquin's
came out simpler Stage I version with about 25 pounds 
of breakaway torque some five years ago, after a solid 
year of development and Peloquin's-style testing - which
is to say severe testing.
In February of 1996, Peloquin added the StageII Diff 
Upgrade with about 85 pounds of breakaway torque, obtained
by further modifications to the brass washers and more preload.
Which kit should you have? Garys advice is, "The Stage I
kit works pretty well for the person with the bolt on
8V, i.e., bolt-on tuning items like a cam and exhaust. 
( Stage I No longer available ) 
Stage II is essential to the 16V owner and to those with 
more involved 8V motors." What's the Diff Upgrade do to 
differentail life? Not much, one way or the other, 
Peloquin stated. It recommends the shims and brass washers 
be replaced at the 50,000-mile mark, or after every season 
for the racers.


THE BOTTOM LINE
Does it work? The engineers in the crowd will tell you that 
even in second gear, a mid 8V motor has more than 850 ft-lb
of torque at the axle, engine torque multiplied by the finial
drive ratio (eg., 110 x 2.12 x 3.67). In the face of that, 
Stage II's 85 ft-lb seems trivial. That's one reason I wanted
to try the mod-just to see if it works.
Flying in the face of all logic, I'd have to say that the 
Peloquin Diff Upgrade works pretty well. I've had Torsional diff's
and the feel isn't all that different under autocross or 
hot street conditions. I was impressed not only with the 
Stage II as installed, but with the completeness of the 
kit as well, along with the excellent, well-written in-
struction sheets. This is a neat product with a terrific
price-to-preformance ratio.
