Looks like that exhaust hanger gets a pretty good workout

Squishy86 · 10-20-2013, 10:19 PM

Lol @ the cone in 1:06.

Burrcold · 10-20-2013, 10:26 PM

That video ruled!! Lol'd at the cone too. That exhaust hanger looks like it's made out if jelly.

feldy · 10-20-2013, 10:35 PM

That's the Perrin Hangers and perrin catback. @PERRIN_Chris These do like to shake a lot huh

front and rear on the konis 1 full turn from full stiff. We run on concete but I have ran this on blacktop and asphalt.

28 psi front
25 psi rear
245/40/rs3s on 17x9 rpf1s.
-2.5 camber up front
-1.9 camber rear
toe a little out in the front a little in on the rear.

Very cool!

You can see how much the rear subframe moves around.

Those tire pressures are awfully low...

Those tire pressures are spot on if you don't over drive the tires.
This weekend I ran the rears at 24 psi. Remember this is autocross not track days.

I got 204 runs and about 4k street miles on these. on the street I run them at 33 psi all day.

Right size rims helps a lot and alignment and the driver.

These are 245s on 17x9 rims. So the shoulder has no pinch and a very slight stretch keeping the sidewalls more stiff. Last year when I ran 225/45/17s on my stock rims I had to run them at 35 psi. When I was driving my FWD car on RS3s I had to run them at 40psi in the front not to roll over.

Andy I will be doing another video with your tarmac prototype springs in the spring.

I run a very similar wheel tire setup and would never run the RS3 that low in autox. I understand you are trying to get the tires to roll to maximize that camber but I think you need less camber and more pressure to be honest.

Whenever I dropped below 30PSI on -2.0F it went from grip to slop. (autox)

I like the video a lot it shows two things, as mentioned by RCE subframe movement and sway bar load.

Racecomp Engineering · 10-21-2013, 06:50 PM

The video reminded me of this one of Aussie V8 supercars. This is a front wheel obviously.

Completely not a comparable car/situation, but just fun to see.

V8 Supercars run a lot of camber, very stiff suspension, and soft tire pressures (in the same range of @feldy or softer). I don't know much else about the cars. But...cool video.

Some of its just driving style. I know a ton of str guys that run the same kind of pressures I do. what works for me not work for you. for me I found a setup that is predictable to my driving style 100 percent of the time no questions. I took one ftdi event this year and the car was not sloppy at all.

Maybe you are right I just feel like those side walls are not stiff enough for those pressures. Guess its an excuse to hook up again for more autox to test!

leon78 · 10-21-2013, 08:13 PM

Cool vid...I have a taller side walls (225/50-16) but I find 35 F is the lowest I can go before to much roll over.... and 32 R w/ almost no roll over on my RS3's.

Seeing this vid also remindes me I need rear sub frame bushings.
