I've had the X73 for about a week now, all I can say is awsome. The car is a totally different beast, not the dumbed down US version. It is very aggressive, mine has lowered at least 20mm front and rear, pics tf. My fender height is 26" fr/25.25" rear, that's at least an inch front and rear. You really feel connected to the car and the road, esp with those solid mounts, not a mod for the gurley man. This is factory racing hard core old school stuff.
The car is very flat during hard cornering. The boys at rpm put -1.5 camber into it with room for more if I want it. With my new MPSC's this is incredible, this is the best mod for the C4S without a doubt. Now this dog hunts!

 

With -1.5 camber get ready to replace the tires soon!

 

I did that for the track, I'll prob back that off a little!

 

Yeah! It is fun though with that camber you can turn on a dime. Enjoy.

 

What camber level would you suggest for aggressive street - but no track - driving with the X73 setup? -0.5? Or -1.0?

 

How often do you want to replace your tires? I would think -.5 would be fine! I'll have to ask my mechanic again what exactly I'm set at (I think it is -.5).

 

I'd be curious to know what the average wear and tear increases by with an incremental -0.5 of negative camber dialed in. Ie, hypothetically, if at -0.5 camber, the tires would wear out at 8,000 miles, at -1.0 of negative camber, the tires are more prone to wearing out at 6,000 miles - or something similar.

wross996tt, do tell us what your mechanic reverts with. I'd like to hear his (and your) thoughts assuming street driving, not track.

 

Unfortunately it probably isn't that simple. Several factors to consider: type of tires, type of driving, conditions of road surfaces, etc. You will set Porsche at negative camber! I know when we originally had my FVD PSS9s set at -1.5 my mechanic said I'd probably get <3000 miles on them. I'll still check with my guy for more info.

 

Does anyone have some general recommendations on alignment specs for agressive street use?

 

Here are some general specs. of course depending on your suspension.

 

Thanks, I assume those are the factory ranges you posted? If that's the case I guess I'm wondering if someone has tried various settings within those ranges to find some preferred settings? For example on rear toe, do people shoot for 5', 10' or 15'? Thanks.

 

A question about camber for tracking. If the track is predominately right turns would the camber be different side to side to maximize right turn handling?

 

I don't think you would want to do that on a street car, could make for some unpredictable handling. On race cars, stock cars for exaple, there are numerous changes on each side to adjust the handling which is biased to left turns. Things like weight jacks, track rods , even tires are different on each side of the car.
