Well I asked a friend and he told me coil overs are the best bet for my C32 but I wanted to ask you guys for opinions....

Thanks in advance!!

good sticky tires and not nitto's

c32used

Tires help but thats why suspension is upgraded to help keep tires More planted to....you can't expect to add stickier tires and traction issues are gone. I want to know for daily driving my car with added boost.

AWDman

grounded during cornering or drags?

any reduction in unsprung weight will help the former and a LSD will help both.

Stock suspension is fine up to at least 450hp.

What LSD's are used in our C32's? Just Quaife?

c32used

Basically Street 90% of the time 10% mixed for Drag and AutoX but Drag more.

c32used

Quaife is the preferred choice but a decent one that gets some credit here is phantomgrip.com its for the SLK32 but supposively fits C32 also.

c32used

At the Rear Wheels or Crank?

neihouma

The reason I ask because I'm in contact with my diff guy who built my diff
for my 95 M3 Turbo. It's twice as much as the Quaife.

HAHA BYE

Jeez how much power did your m3 have to the wheels??

AWDman

phantom grip simulates a torsen lsd....the quaife works a bit differently, it can transfer 100% torque to wheel with grip. the torsen and phanton function like a locked diff so both wheels get 50%......(i'm not sure i'm 100% correct but may be this will cause you to investigate further which is the intent).

AWDman

i'd get the quiafe. it even has a warranty if installed by an authorized shop.
surf onto quife's website. personally i would waste time with anything else.

neihouma

Last I recall 528RWHP & 542RWTQ @ 22psi on a dynojet. I loved the diff
because whenever I made uturns my back would hop like a bunny (that's
when I knew I had 60% lock up TRUE LSD)

A copy n paste from my convesation with my diff guy.

HAHA BYE

I have the quaife and personally love it. I drove a c32 without one the other day and wow what a difference. Its worth every penny

What is a Quaife ATB Helical LSD differential
The Automatic Torque Biasing Helocal LSD differential is Quaife's unique patented design, and is an after-market differential that provides smooth, constant traction for racing or slippery road conditions.

Suitable as an ideal replacement for any front, rear or four wheel drive application, these ATB Helical LSD differentials have the added benefit of no adverse effect on the steering of a front wheel drive vehicle.

Quaife ATB Helical LSD differentials have been used in a wide array of applications, from Formula 1 cars to emergency and public utility vehicles, where all weather mobility is essential, and where the product must perform in the most demanding of conditions.

Available to suit a very wide range of vehicle applications, from Alfa Romeo to Volkswagen and including Ford, BMW, Honda, MG & Rover, Vauxhall/Opel, as well as a range of light commercial vehicles.

The characteristics of the differential are that it progressively locks as torque increases; there are no plates or clutches to wear out, as the more conventional limited-slip designs incorporate. The ATB Helical LSD differential is particularly effective in combating the effects of FWD torque steer and understeer.

Quaife Engineering also offer their ATB Helical LSD differential with a limited lifetime warranty [see terms and conditions], as a demonstration of the quality of the product.


The Ultimate Differential

The Quaife Automatic Torque Biasing Helical LSD Differential enables your car to accelerate quicker and corner faster. How?
Simply by getting the power to the ground!

The Quaife differential powers both drive wheels under nearly all conditions, instead of just one.

With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.

The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In cornering, while accelerating out of a turn, the QUAIFE biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife differential also controls loss of traction when the drive wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife ATB Helical LSD differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife ATB Hleical LSD differential's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage, whether you are on the track or on the street.

The Quaife differential is extremely strong and durable, and since it is gear-operated, it has no plates or clutches that can wear out and need costly and regular replacement. There is no maintenance required to the unit, so once installed the unit can be forgotton, apart from the better road responses.

The Quaife differential is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the cars towards its limits.

The Quaife differential is proven in everything from SCCA Rallying to drag racing and Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort

AWDman

the friction type (salisbury) may be more noisy and maintainance intensive from what's i ve read

If anyone gets serious about making a purchase please post first to gain interest in a group buy. I for one would be interested.

Eurocharged Rick

if you guys are interested, let me know...i can setup a group buy for the Quaife

c32used

1. C32used has interest if priced right

c32used

Thanks....this is the reason why I ask.....keep it coming!

c32AMG-DTM

With the common number thrown around for an installed Quaife to be $2,000 - $2,500... all I can think when reading your post is "yikes, four or five grand for an LSD, ouch..."

neihouma

It's priced at $3500 total shipping included, labor is another story. Evosport
sells them for $1800 + s&h. I don't mind spending that much. My diff costed
me almost $2,500 for my 95 M3 Turbo back four years ago and it's worth
every penny to me. I've had nightmares with my Torsen diff on my IS300
Turbo, thats why I'm staying away from the Quaife.

OZAMG

The Phantom grip as it states on their website simulates a disc-type or more commonly called a Salisbury which is a clutch type LSD. The Quaife is a Torsen.

I found some good write ups here is a link

What problems have you had the Quaife? I am going to install an LSD next year and as options are limited I am looking at the Quaife and Phantom Grip.

The Quaife is a Torsen style and provides better torque distribution between the wheels especially when turning, and is top of my list so your experience would be interesting,cheers
