I'm expecting a fan assisted blown diffuser that maintains constant ground clearance and acts directly on the wheels (rather than the chassis).

If you want some info on the above let me know. A guy was building one for a Elise on another forum. They reported amazing results from it.

I'm on here because I race in ST2 and can't have any more hp, so I am looking at any other opportunities to lower my lap times. Jerry

Here is the thread for the blown diffuser for anyone that's interested. They recon it was making about 1000lbs of downforce at low speeds!

There a quite a few pics and it's more the technical information that's the good bit. Best waiting for the reg to go through and then Read the thread. It's good.

most of you all have seen mine but for those that havent:













front undertray (the finish is straight from the mold - probably wont get clearcoated since you cant see it):





The plan is to install everything this spring...

Yep main body and fences are all CF and kevlar reinforced plastic from a single fiberglass mold so everything can be replaced. The gurney, mounts, and front undertray came from lost process foam molds.

Its not a difficult thing to do (just takes a little practice to learn how you need to work and plan things out) and not extremely expensive if you have a local supplier; the online stores bend you over on their pricing for cf - 50 to 80 bucks a yard is a rip off (you should pay around 30 to 35 for 6oz and 40 to 50 for 11 to 12oz carbon; kevlar should be the same or a few bucks cheaper than carbon). As far as resin goes, smooth-on brand laminating epoxy works well and is MUCH cheaper than West system stuff...

Id definitely start with fiberglass and polyester or polyvinyl resin (should only be 30 bucks a gal) just to make simple objects as practice before going to more expensive materials like epoxy and carbon.

Not too hard unless you try to mold/layup a C6 headlight bezel...... Now I know why they are 1500 a set.
