Whats the choices on lowering a 997 turbo correctly with pasm ? thanks

 

Springs or coilovers. Unlike previous suspensions the pasm responds well to lowering springs, a great bang for the buck mod if you will. The most used are Techart, H&R, GMG and they all seem to work equally well . I found the H&R gave the most drop, which eventually became an issue with my particular driveway.
I now have the Bilsttein B16 coilovers set to close to stock height. This setup works for my driveway situation. Trackwise they are very close in terms of performance. I doubt there would be significant differences in lap times unless you went to a hardcore suspension like Moton or Penske. All in all I like the height adjustability of the Bilstein setup.

 

I use these...works great, and the lowered ghetto look attracts all the chics...

Oh...wait...you said to lower the car properly, huh. LOL

 

We've installed H&R lowering springs on several Turbos and have been very happy with the results. The PASM system actually responds very well to lowering springs. Not to mention that they are a bargain compared to the cost of coilovers.

However I'd say it really comes down to how you intend to use the car. If it's strictly a street car (daily driving, with a few occasional spirited drives) I think you'll be completely satisfied with just lowering springs. If you're going to track the car often and you want the ability to fine-tune the ride height then coilovers are the way to go.

Feel free to let me know if you have any questions about any particular setups.

 

How is the ride with the H&Rs? Do they make the ride stiffer, harsher or bouncy? Will the stock shocks bottom out with them when the car goes over a big bump? I just want to lower my car, and am not planning to track the car.

 

The ride with the H&R's is great. Slightly stiffer then stock, but still very comfortable. You also retain the PASM functionality, so if you want to stiffen it up a little, you can use the sport setting. The shocks do not bottom out at all. For everyday driving and even occasional track use.....you will love them.

 

Thanks for the quick reply!

 

You're welcome. These are in stock too...

 

I used the H&R's several times myself, hey are great. The ride can be stiffer or softer depending on the spring rate... I just wanted to throw this idea out there, not trying to mess with your post Tom

 

No problem. I'm glad you mentioned that. We offer both the standard H&R lowering springs as well as the Champion Motorsport lowering springs. Both achieve the same ride height, but with slightly different spring rates.

For casual use, however, the average user may not be able to tell the difference. Also knowing how the roads are in the great NYC area...I'd say stick with the slightly softer springs. If you want to go stiffer, you can always activate the PASM.

 

So the Champion springs are basically H&R springs with stiffer spring rate? Does H&R offer different spring rates on their springs?

NYC roads suck the big one, which is why I never take the turbo into the city.

 

The Champion springs were damn good, my only issue was driveway clearance, the front drop was was about a 1/4 more than I could deal with.

 

Correct. The Champion springs have a slightly higher spring rates. the H&R springs are available only with one rate. The difference in rate is minimal, but still slightly noticeable.

I'm originally from the NYC area, so I know all too well about the roads. Not to toot my own horn, but I'm pretty confident that my advice is sound because I know what types of roads people in the NYC area have to deal with on a daily basis. I still have nightmares about the Cross Bronx Expressway.

 

i have the techart springs really happy with them and no clearence issues i think its a 15 mm drop .Car rides better and sport mode is transformed not so bouncy as stock. Reduced squat under accelaraton and braking. All in all great mod for the money. Car should of been like that from stock.
