Question about driving...

[emperorphobos]

Hello everyone.

 

I recently got a 99 C4 Cab. It's my first carrera and comes after owning for many years a Cayenne S (2004).

 

The car was in a very bad condition when I bought it (left outside for more than 3 years from the previous first owner) and it's gone through major mechanical/electrical and cosmetic repairs (so far more than 10K), including gear box, brakes, new tires, maf, clutch etc.

 

After 2,5 months in repairs the car it's clear from computer checks, but I'm having the following issue (?) when I'm driving. I feel the car as you accelerate light on the front part. Actually the more I go above 50 the lighter it feels. I never gone more than 80 I feel really scared. There is nothing wrong as my mechanic told me and he insists that this how these cars are running (he's also having a 997 and tells me that mine drives better than his).

 

Maybe I used to drive the heavier and more stable cayenne but I believe that this isn't how a porsche should handle. Car is on 68K. Maybe are the shocks? Or just my idea?

It sounds like an alignment issue to me.  If you haven't had it done, get a good 4-wheel alignment check, including ride heights.

Many things can affect the feel of the car at speed.  Have you ever driven RWD with rear engine before?  Tire sizes and fills.  As above, alignment.  Possibly shocks or mounts.

Thank you. I'll go for an alignment. Is it true that its best to do it on dealership? Statman I had with a very bad experience (20 years ago Lotus Elan), car ended totaled.

try putting some weight in the front compartment.

try coil-over shocks.

alignment can't hurt, and wheel balancing,

but you don't describe any shimmy in the front, so I'm not sure an alignment is what you need.

Sounds like you've got the rear wing without the front split. That would make the front very scary about 80.

1) Alignment.

2) Quality, matched, tires that are less than 4 years old, properly inflated, road forced balanced, and in the proper direction of rotation (if applicable).

3) Make sure rear spoiler deploys at about 72-75 mph.

4) Start shopping for new mechanic

I done alignment, tires are brand new and the rear wing is working. Probably new mechanic is the issue or maybe shocks.
