I have 968 sway bars and shocks put on by PO.

When I accelerate the car squats. When I brake the car does NOT dive.

is this likely a problem with rear shocks or something different?

what's a decent not too expensive solution? My car is 99% street and sees track once or twice a year, so i don't need the best of best suspention system, just a good one.

Thanks.

 

How many miles no the car? I had an 88 turbo s with 80K on it that the rear torsion bars were completely shot. The car would squat till it hit the bump stops on acceleration. The previous owner had told me he loved accelerating on the highway every day going to and from work. New torsion bars fixed the squat problem.

 

I had the same problem. Replaced the stock shocks (which were very worn out) with bilstein HD's and the problem has greatly reduced. The drivers side shock had zero life left in it.

 

Yea I had that squat, not much fun going round corners.I put in the 968cs shocks and helper springs.

 

I think its a characteristic of the car. My 968 with full Bilstein Escort Cups 350F/400R still squats with my measly 236hp...if that. I've been in a 951 with Ledas and about 350 at the wheels and it about did a wheelie. If it matters, my torsions have been removed, so no problem with the being worn out!

If they are new koni's try to adjust them to a stiffer setting. Even though most hear say that they adjust rebound only. I beg to differ.

 

Your shocks could be blown or very worn out. New ones will help, however a stiffer spring rate/torsion bar rate will help quite a bit too. The only issue is it's not exactly a cheap or simple job to upgrade torsion bars, and coilovers really jack the rear ride height up quite a bit. With rear coilovers you pretty much need to reindex the torsion bars anyways. I'd try putting in new rear shocks first, and mess around with adjusting the dampening as this is the cheapest easiest route.

 

My car squats too (stock 1987 w/ 65k) my guess is the Shocks are done as well. I know replacing them won't cure the problem entirely but should help. I think these cars ar supposed to have some squat on accel in order to deliver more grip (weight transfer) to the rear wheels. I suppose the reason it doesn't dive under braking is that all four wheels participate there (as opposed to rears only on accel).

Without getting into the geometry of the rear suspension, the reason for squatting is low rear hight.All US-spec 944s have lowered rear hight in order to comply with bumper-hight regulations.By rising the back of the car (done easily with the spring plate eccentric bolt) I eliminated squat and my car has more natural "leaning forward" look.

 

I had the same problem, it went away when I upgraded to full bilstien Escort Cup Coil overs.

 

kos_007 just an FYI you have it backwards, U.S. cars are higher in the rear and most lower to Euro ride height.

 

The rear is undersprung. Porschefile is right. Increase your rear spring weight or you'll have to live with squat or a stiff (damping) rear

 

I have 28mm rear bars and newer shocks in the rear, it still squats a bit but much less than it did.

Front dive under braking has nothing to do with rear squat and is a function of suspension geomitry.

 

^^^^^^a shortened version from my SAE automotve chassis book. For those with the means look at page 260 of "the Automotive Chassis" published by SAE and authored by Reimpell, Stoll and Betzler (2nd ed.) It has an excelent diagram and means to calculate squat under decel on a semi trailing arm rear, reverse some of the forces and you can get the squat under accel.

 

asmi951 has it "Front dive under braking has nothing to do with rear squat and is a function of suspension geomitry."
The rear suspension geometry of trailing arms makes the chassis naturally want to squat with trailing arms, camber plays a role too. Shocks and torsion bars will help, however to combat anti-squat effectively is to do what Porsche did and make a multi-link rear suspension. The multi-link rear suspension converges the pivot axes in order to compensate for the weight transfer.
