I can't decide:

1 - "R" lip and 3-4" splitter, full undertray.

2 - GV (knockoff urethane) lip and no splitter, full undertray

3 - GV lip with splitter, full undertray

4 - Other (mention below please)

Car is mostly dailied, my main reason for aero is highway stability and looks, trackdays when I can afford to (years from now).

TIA

 

I vote #3 but didn't you already have one?

I voted for #3 but my setup is basically #2. I'm planning on adding a splitter soon, my car is track only though...

 

I had an authentic GV (other option wasn't out yet) and it developed some big, authentic cracks... My biggest concern with 3 is ground clearance.

 

hard to say without seeing your ride height... GV lips only look good to me on a slammed car. Since you're even considering a splitter, I'm gonna say you're not that low, so I vote #1 on a daily driver

 

4, Rharris RB bumper and wood splitter.

 

i voted #3


but then i read hustlers post and now say go with what the god said!

 

Entirely too baller, sir.

 

Rharris is making an RB bumper?

Dont get down on yourself like that.

 

3. I will end up with the same, probably. Right now I have an H-D racing "lip"/air dam, no splitter. May just add splitter to it if it doesn't drag.

 

 

Fap fap fap splouch

 

Is that an actual finished product? Looks good!

 

I still want that bumper that Rob was talking about doing for the track guys... Sigh... If you want a RB front bumper, get ahold of John at Axis Power Racing. He has one he is trying to sell. Pretty reasonable price too and is in decent shape as I saw it when I picked up some carbon parts a month ago...

However, for your purposes as it will be daily driven and see little track duty... I vote #2.

 

Does anyone have any measurements comparing the difference in ground clearance between a GV and the R lip? Even though the votes are 9-6 for a GV, I think for ground clearance I'd better use the R. After all, I (read: my dad who, in his defense, hadn't driven a low roadster-type car since college) smashed up my GV and adding a splitter could add up to 3/4" on top of that.

OTOH, #2 is basically what I had before (plus a bit more aerodynamic functionality), and I've raised the car 5/8" since, and the knockoff GVs are much more durable. Plus, I'd wager the undertray material wouldn't need to be as thick if it were an actual splitter.

Here are a few shots to show my height:

 

I'm impatient, just bought a knockoff GV. Going for #2, as I can easily morph it into #3 for track duty later and keep it streetable with the lip off.

Where can I buy the plastic for the undertray?

 

I've looked in the past and found tons of online sources, but it's been hard to find local suppliers.

So how much undertray are you planning? IIRC, there was some debate about running a full tray because it could keep the airflow off the trans and dif.

 

As much as neccessary I guess. I'm going to do more homework on it when I get home this evening. Searching from iPhone is less than ideal.

 

That car is so nice.
