The race class i race

there is no regulation of what kind of wing or spoiler you can run on the race car


so i want to really use this to improve my lap time

but being a first gen racer. there is not really any aftermarket suppport you can find on the

market

so a lot of time you want to some thing . you need to build your self


so what i think is, if i want to build some thing out, i want to go all out . that i dont regret


here is the result i come out~ this bad boy is 196cm wide n 15 cm long from lip n with build in aero pocket to speed out the air that suppose to increase the down force even more

cant wait to test it out. [ my next race would be at sep 30}




I also mold from it, so if any one is intrest in it can also PM me

That should keep the front end nice and planted! Nice job!

You're going to need a pretty massive rear wing to keep it balanced, but I like the initiative you took to make your own parts.

Cool project! Nice work.

Are you allowed to run the wing higher than the roof in Time Attack?

I hope the mounting is well braced. My splitter is hung from the front bumper tubing I replaced my stock bumper with. I have cables linking it up and it is made to pivot from the rear mounts just in front of the front axle. (that way I can run over things and the splitter just bounces up). I can stand on the splitter and I'm 245 Lbs. I did a very rough calculation based on spring compression in pictures at speed and I believe it is generating close to 150 lbs of downforce on the front at 100 mph.

Basicly in my Home country's the Class race. the rule is pretty much open~. most of car i race against is ex WTCC BMW 320 !!
but as for aero those car are self limit to wtcc regulation.. but not for me. i will use what ever i can to keep up !!

with size of front spliter i have, i should be generate over 180lb of down force at end of straightway

so after i mount it . i will try to see if bracket can hold up to 200lb of weight

you have pic of your mount ?

First shake down of my Flying Tiger

due to the drive shaft problem. i cant really have top speed i need. thus my lap time is a bit slower the n my best record

but as for front diffuser. it feel great. i can really flying into those high speed corner with no worry!!!!

That looks really interesting. I love the integrated front diffuser. Good luck with the work and I really like the look.

Also, what country are you running in? That last photo is pretty hairy running so close to a wall with no barrier. You guys are very brave.
