I'm running a fixed techart "whale tail" type spoiler. I did it for looks more than anything. Am I looking at big problems switching the lip out...

My car is kind of a hybrid. Supercharged C2. Lowered on PSS9's. Techart fixed tail. Turbo nose. Turbo look rear bumper. And factory side skirts.

Am I really going to notice anything by switching the lips around since my car is so mismatched anyway?

 

My turbo came with a c4s lip for the same reason (previous owner was tired of scraping and destroying the oem turbo lip). I removed it in favor of the Aero kit lip when I got the car. I much prefer the look and have been driving lowered cars for a long time so I ditched the c4s lip. It's then when I noticed the c4s one had been damaged a bit as well lol (on one of the sides where it's lower). It's not a bad look though, IMO; definitely more practical for street driving.

 

Newbie question, are you guys painting the lips, both the c4s and the turbo lip, or just the aftermarket ones. I too need one but don't want to tear it up. I suppose the CF ones are just as east to damage?

 

Since that was my car pic way back at the begin of the thread ......my 2 cents....as you can see that lip is painted (with holes filled).....but that car has more than that painted over .
If you have a dark color car, I guess I wouldn't bother painting.
On the aero impact......the car pictured is very stable at 160....whatever.

How a car handles at speed is the product of many factors.

 

Mine's been safely tested to steady state speeds of 140MPH, even with my GT2 rear wing! And no, I was NOT on a recent episode of cops!

stick with the Turbo stock lip. Once you get used to taking driveways at angles, you'll be fine

 

My car is a bit low and I use it for street cruising, canyons, track, etc... The first thing I did was switch to a C4S front lip and had it painted silver to match the car... It clears a lot better than the turbo lip but mine still takes damage occasionally... It usually holds the paint and I just retouch the lower lip when I hit it badly. Recently, I nailed it pretty good in an alley and now I'm going to repaint it and the front bumper (rock chips bothering me). I figure the lip and front bumper will last a solid year between repaintings... It all depends on where/how you drive and how low your car is. I can't comment on the aero factor but I am running a GT2 add on spoiler for reference...

As commented above, there are lots of variables that come into play when you are talking about high speed stability. Aero work is definitely a big one but it's not the sole variable! A sorted suspension should help, not to mention a lowered car with a slight rake (I'm corner balanced after a RWD conversion).

 

I've had it for years now... Either I suck or it's just not workable

 

Very good points... I believe the proper suspension setup goes a long way towards helping ith some of these aero add-ons. However, once you get into the 150mph+ range, things change and all betts are off... I was at VIR doing in excess on 170MPH on their long backstretch and got a bad high crosswind that caused the car to change lanes. HUGE eye opener! That was with the Aerolip and the GT2 wing.
