Rake

[8RZ]

No, it's good for launching in reverse.

I was running a slight chassis rake for a bit, mostly for the aero benefits listed above, and the slight aesthetic benefits 😉. Got rid of it though, cause it was causing the front of the car to be just low enough that I was scrapping more then I liked coming in and out of some driveways. Car isn't crazy lowered either, maybe a hair over 1" from stock.

Oh and I'm running a square tire setup.

Rake can also be used to alter suspension geometry in a way to reduce understeer. That can be a benefit if done right. It should still be kept fairly subtle though.

I don't recommend different size tires front vs rear for most people.

As a follow up, if you were to prepare a car that had some rake, (say a spirited DD or something,) how much of a differential in height would you use? a couple mm at most I'd imagine, (3 or so?)

If we're keeping it theoretical, the roll axes on the Lotus Elise were set up such that having a positive rake of 5mm [front 5mm lower than rear] gave the best overall balance; roll center axis and aerodynamic effect with its flat floor.

Looks like a little rake on these:






As long as you don't go nuts it should look OK.
Mind you I come from a generation that did this to our street cars:

That's about the difference I have on my Forester XT, it helped keep things from touching on launch at autox and kept the rear gripping and the COG down.

That sounds like it'd be REALLY bumpy...

Here's an old pic of mine:

I think that top picture is along the lines I'm looking for, with the height of the release series below. Not looking to go much lower than stock.

This is almost exactly what I'm going for stance wise. It's subtle.

Come on....go gasser style

I have a bit in mine. Not a tonne.

It looks good!
