The car is a 2003 Turbo lowered 1" on H&R's. I have the alignment specs somewhere if pertinent. Two different sets of new tires: Hankook Ventus V12's and Pilot Super Sports.

When I am holding a turn and putting a little (as in little) power into it the front end will feel like it is slightly rubber banding left to right.

I had this same feeling but more in the rear when I lowered my Z06 a little too far, but from what I'm reading 1" drop is very safe with the stock shocks.

So is this feeling normal? Is it something I can tune out with adjustable sway bars?

 

sounds like hankook v12's to me esp before being scrubbed. are you pushing the tires?

 

That's what I was thinking but now I have the Pilot Super Sports on there.

 

well, it was a great way to describe new 'kook v12's. never again for me. sidewall flex to the max. michi's no prob.

 

Ditto on the Hankook's. Made my car handle horribly, and I damn near crashed doing a simple lane change going about 65 mph.

 

Could it be a tire pressure thing with the V12s? I've had to track with them several times this year and don't get your symptoms. I do however get them greasy within 10mins then they loose grip, but seem to at least hold up structurally.

When I ran MPSCUPS they were a MUCH harder sidewall and you felt every crack in the road/track.

 

The car has Michelin Pilot Super Sports now and I am still getting this uneasy front end so I am not blaming the Hankooks.

 

I chunked my hankook v12's after a few laps back when PIR was still open for DE. Suckers got hot and started flaking away, practically ruined them.

Switched to much softer tire, but still not an r-compound and I didn't have anymore issues.

 

How many miles on the car? The stock suspension may just be worn out. Hard to tell. I would scrap the reason being the tires since you already swapped them out.

 

67k. As far as I know it is on the original shocks and struts. I wouldn't be surprised if the fronts were softer than they should be but the car certainly isn't riding like they are shot.

 

On a side note, the V12's do have a relatively soft sidewall and get hot/greasy fast. Works fine for medium street performance but they do wear out fast. I changed to g-force sport comp II for my GTI. Much stiffer sidewall.

 

+1

I would then check the control arms and bushings . If they need to replaced I would upgrade to the GT3 RS Lower Control Arm Kit.

 

I'll check out the bushings when I do the radiator in a few days. I won't be happy if I find worn bushings since I just bought the car and had a PPI done but a local Porsche specialist.

 

That would also make me not a happy camper ether, the only other thing I would consider is upgrading to H&R Sway Bars if you haven't done so already. How are you liking the 996T so far ?

 

Sway bars are probably my next mod... just hoping to hold off on mods for a little while.

Overall I am loving the car. I have only put about 350 miles on it and it already feels like home and fits me like a glove. I always knew it was the car for me and never even drove one until the day before I bought this.
