If its dry out atleast.
GTI: My spring rates (8k/10k) are ok for daily driving, not too much worse than the stock EVO 8 suspension. Big whoops on the freeway kinda slam your kidneys but that's about it. It's not plush; you can ride in my car if I ever get it back together.
Bigger rear swaybars actually remove traction from the rear to change the balance. I have a 25mm Progress Group (builds them for Perrin) adjustable rear bar and I have it set to the lightest position - and my car still gets loose off throttle. With it set any higher the car power oversteers like a butt-rock rear wheel drive car. Although it's kinda fun for dicking around and being a douchebag on the streets it's outta control at the track. I'm going to play with rear rebound settings at the track to simmer it down a little.

You're right on the traction thing on the sway bars, they actually push on the lifting side, forcing the tire to the ground, but the actual process to function takes a book to explain, instead of a paragraph on a forum
I put a Hodgekis 25mm bar on the rear, set to medium and that rear end sway totally went away trail braking. I only have the stock MR Bilsteins with stock springs though, so I know it's all going to be different again with coil overs.
Yeah, you got me, I did type your name wrong, but immediately noticed it.
Jake, no worries mate...we got it
But just to clear a few things up:
This car is not out of fuel, it has a stock O2 housing on it, it was going a little rich by redline but because it didnt have a WB in the car I was doing it the old fashioned way. Even then the AFRs are very linear but far from pig rich (a little rich from 6200 to redline). 28psi at peak torque is far from maxing injectors versus something like 28psi at 6k, which this car is not doing. Here is the dynosheet I was sent, and you will notice that the car seems to be blowing the WG open and not holding boost to consistent.
If it were out of fuel the AFR numbers would be lean not rich.
The first 2 pulls are 3rd gear pulls and the last is a 4th gear pull that was started really low and loaded the boost way up. We normally start our 4th gear pulls (if we do them) about 4k, but as you can see this started at 3k and spiked rather high.
It is not the valvetrain. S1s do not require valvetrain modifications, and as far as that goes I revved mine to 8300 for a whole season on S1s and only lost 10 lbs of seat pressure measured at bind.
Timing is pretty good on this car actually, looking at his map and logs the car is still run 15* out the top.
We'll get it at the dyno day when we finish our EPM test. I am confident that with the stock O2 gone and something that flows better the car will make the power it should be. IXs that make 330+ have all the bolt ons usually. I can only think of 3 or 4 cars that have made over 330 (on stock cams) and none of them ran 22psi. All cars taper, the big boost has more to do with torque and overall shape of the powerband than what boost its running at peak power on a stock turbo as they almost always will drop to 20-21 by redline.
Stock turbo cars that make ALOT of power are all running LARGE cams and meth, ethanol, or racegas generally. The large Hp pumpgas cars have the M2/M3s, S2s, BC280s, etc.

THAT WHAT A REASON missed.. I thought U HAVE O2 dump installed JAKE!! no wonder u have stock O2 housing.... get change asap...
No Billy im not talk about valuetrans to get more powers.. i talk about how can REV harder...

Jason I have same Birany (jared) set up.. KW V3 coilover with 8k/10k...
But it ride hella good and stiff and drive hard on corner.. but i was thinkin about stiff more Body.. like less body twist.. maybe need underbrace? or sway bars.. but i have rear Strunt bars.. maybe roll cage help? i was plan to install soon..
