photos of rear diffusers and front splitters - particually Strikers
Hi all.
Following on from
http://www.locostbuilders.co.uk/forum/4/viewthread.php?tid=178791
I am looking to get as much advice and photos on how to fit a rear diffuser on a RAW Striker.
Im hoping that the Diffuser I have got (Plays Kool) will be reasonably easy to fit but the more info the better.
Cheers all.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Heres how I did it, I used the seat mounting bolts along the floor with a piece of 2" wide ali, couple little brackets each side bolted to the
body and positioned the fog light to hold it in the middle. I opted for it like this to allow air round the diff and whatever was coming down the
tunnel from the front a direct exit out the back.
Then painted the whole lot black..

General concensus in RGB paddock is that 12-15 degs is best angle to to have rear floor

IMO From doing some aero work on floors, i'd say more like 7-9 degrees for the ideal downforce vs drag.

this is my rear diffuser, i've no idea on the angle - all i know is it covers the floor area of the boot panel and stops its acting like a
parachute!

7's aren't exactly 'aero' though are they?!

Eddie, what did 7-9 deg work on? I've seen diffusers from 0-90deg work best on all sorts of different things in different situations, just
giving numbers isn't that helpful in reality.

True, That was on our delta (LMP styled) and found similar on our seven styled car. Agreed its very complex though, I found running a wing you can run
more of an angle too.

What ride height were these tests at ??? We are just about to start work on the rear bodywork of the GM3, and want to integrate it into the rear
undertray

while on the conversation of diffuser design the plays kool one i have is curved so varies in angle. how does that help? also it only has side
vertical fins and no others. does this matter?
ultimately Im only doing this for looks and any difference made at top and is a bonus.

Gradually curved seems to give better results compared to an abrupt flat to angle, but again all to do with ride height floor shape, rear body work
etc.
Best bet is to make it adjustable

A gradual curve will be better than just a bend. Mine is bent around 12 degrees, this is largely due to the chasis and bodywork design.
A friend in the know, says the difference between a few degrees and curve or bend will be minimal, and probably not worth worrying about and any form
of undertray will be beneficial.

Abrupt bend isn't going to make a huge difference, I am quite sure, but can make life a lot easier when it comes to making strakes.

Not sure if I am hi jacking your posts , but thought this might be a good place to start instead of starting new similar thread.
I have a Westfield that I want to fit a rear diffuser to, however it is an SEI, and the rear wishbones seem quite low to me, and I think they would
foul any diffuser.
Has any one any experience of fitting one to an SEI or any suggestions please.
