any prelude owners installed a rear diffuser and tested it at the track??
is it worth it or does it only saves you like.001 of a second?

 

who makes one?

I will be making one for my 4th gen

prelude bumpers are like giant paracutes it would defintely help all aspects at higher speeds.

 

i was going to do it my self...
i own a 5th gen...but that would be a drastic change to the back of the car...
just wanted to know if it was worth it.

 

i think a rear diffuser with a underbody tray and a splitter would make a big difference. i've been thinking about fabbing one, but then i realize i don't have the tools or the resources...

though if you feel compelled to make one, satan, i wouldn't mind doing some "testing" for you @ willowsprings, Laguna Seca, and BW...

 

really, all you "need" for a rear diffuser is a 3" or 3.5" hole saw, a drill, and a tape measure. just measure out where to cut the holes, and cut them. you done really need the billet or carbon fiber plate, it just cleans up the look from the holes. most *cough*streetracers*cough* i know usually just cut the holes out and dont worry about the bling-bling.

 

how about the underbody covers too. doesn't mugen make them for the s2000?

 

IF this is for track use only why not **** it, take off the whole back bumper?

we're not talking about cutting holes in the bumper...I was talking about filling inthe entire underbody...

 

Why not just take off the back bumper? Holes in the bumper look like ****. By the way satan_srv my car didnt have a oil dipstick. I have to order a new one, and being new to owning a prelude i had no idea where the oil dipstick was. On all my previous cars they were near the heatshield/header.
