My car is taken apart for on-going motor build shake down crap (fixing leaks). And the tracks are closed.

I plan on lots of track time this up coming season though. I've kinda given up on trying to produce the parts though - I'll just be testing for my own pleasure.

 

ok fair enough, at least ur not like certain forum members testing intercoolers haha.

 

could I ask a stupid question... what thickness aluminum did you use?

I'm building my own splitter as my APR one ripped off on part of an oval on a track we have down here in socal.

I've heard people mention alumalite which sounds promising except I can't find anyplace that sells it...

 

^You might to ask around about that on the corner carvers forum.

 

Are you planning on building the splitter out of aluminum? Alumalite is just a core material that can be used with carbon fiber or fiberglass.

The thread below (linky) talks about the modifications to my APR splitter. I bonded .063" 5052 aluminum to the stock APR splitter and then mounted it to the chassis with brackets on the radiator support and cables.

I've been following ur various threads pretty closely. Impressive and inspiring...

I have considered your method. .063 is roughly 14 gauge. how did you come to 5052? How does it compare to 6061 or 6063? Given I've already got an apr splitter it seems a logical way to go. My concern would be flex. If you were to get your car up to max speed, do you think flex is an issue? Given the way your support cables work I'd think not...

I've never seen alumalite but I've read about it. Seems like pretty thin sheets of alum but a friend of mine was raving about it when he saw it.

I've thought about laying my own fiberglass but working with fiberglass is about as much fun as taking a bath in sandblaster...

 

5052 is common grade aluminum. 6061 is stronger and stiffer, by nearly two times, it also costs about twice as much. My decision came from the fact that I had a piece of .063" 5052 sitting in my garage.

Overall I'm happy with that grade and thickness. I used rivets along with the adhesive to make the bonding robust. I've done unplanned bulldozing with it and it hasn't even had a problem holding together. It has already seen 3 track days and 135 mph speeds without issue. The overall bonded structure doesn't flex much at all- it's stiff.

Getting it mounted to the chassis is really the key.

 

Sounds good. Chassis mounting I'm not to worried about. I can tig as well, even thin alum and I think I've come up with a scheme somewhat similar to yours except with less reliance on the radiator support as a mount point.

guess I should fire off an epoxy order...

thanks again

 

Any research of those canards actually do anything? I've always wondered that on thse cars, that a tiny air foil like that wouldn't be able to provide any noticable force at the corners of the vehicle. This is where aero testing is required IMO. Maybe a zip tie around a strut to see if the strut travels any farther down on an ultrasmooth road or something, but I'm just not sold that they're functional. Just curious what you thought Jared

 

I haven't been able to get time to test them. Really they are there more as a tuning mechanism for when the setup is kinda finished up and just the little details remain. I still need to finish the GT wing and rear diffuser. Once that is done I'll install the downforce measuring sensors and fiddle with stuff. Probably won't have that all done until next year, as I'm running out of track days this season. All the clubs I run with kinda stop after August, at least at PR, which is lame. I'll probably head down to Portland or ORP in September/October.

There are factory threaded holes on the vertical areas of the radiator core support on the frame (think above the ends of the IC). I don't use them, but you could create a bracket that mounts there and then hangs down to pick-up the splitter. Voltex does it I believe.

 

they run four metal straps, two per side on a bracket off the area where our front crashbeam mounts down to their splitter. They also run a piece of what 1" (i think) square tube laterally attached to the splitter and two of the straps attach to that.
