What is best bet to keep suspension grounded during power upgrades?
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!!
Thanks in advance!!

for my 95 M3 Turbo. It's twice as much as the Quaife.

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).

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.

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.

thanks- i stand corrected. here's a paste from quiafes site
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

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.

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

It's priced at $3500 total shipping included, labor is another story. Evosport

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
