Thanks! I think the 18x8 wheels greatly add to the agility of the car with a grippy tire and proper alignment. The Raijins aren't the lightest 18s out there, but they are a good wheel and a good price. A good suspension setup and alignment are key to keeping the stock handling characteristics.

After lowering the car even 22mm on RCE springs I think that camber correction and alignment are crucial to keeping the predictable tendency to progressively oversteer with wider wheels and tires. Snap oversteer is a risky side effect of lower/stiffer suspension without rear camber correction to get the contact patch of the tires back to normal.

You have one sexy ass car! Keep up the good work!

No more chirping fuel pump! Hope it stays that way.

Nice! My dealership won't change mine out. They "don't hear anything". I just play my music or rev my engine loudly. It's annoying if anyone else notices and comments on it, though.

Is your dealership fairly compliant with your wishes?

Yea thankfully they agreed to do all 3 TSB's with no issues. Mine was chirping loudly and it was obvious that it was coming from the HPFP. Still no chirps since replacement, but I won't be convinced that it will never chirp again until there's much warmer weather where the noise develops most frequently.

Really looking forward to getting my car on a lift and installing these new bushings.
I used some Christmas money to pick up Whiteline's rear crossmember mount insert "positive traction" kit and Perrin's shift bushing.



I've read really good reviews about these two and they should be an excellent combo. Now I just need some time on the lift that's currently occupied by a 944 that needs a clutch, so it'll be a while...

^ Whiteline makes fantastic bushings. Looking forward to your opinions on them. You may be waiting some time for that clutch, last I heard it was around a 15 hour job?

Lol yep, prettly much every single moving part in the drivetrain behind the bellhousing has to be taken apart and put back together. The big downside to a transaxle/torque tube design. It's my Dad's 944 S2 club racer so I'll probably be helping along the way to get it ready for next season.

For the clutch? You just have to remove the driveshaft, which is easy. Then it's all normal stuff, clutch hydraulics, removing the shifter, then the trans. Shouldn't take more than a few hours with a couple of beer breaks

I 100% agree with you, but I just can't figure out how some people can "get away" with it while I couldn't.

You're right, though, it's OT, now! haha

Ugh, this car is so nice! I'm so debating the tail light mod, but I'm not sure I really want to go that route. I don't mind cutting them up, but I really want to try painting my tails red and then doing a night shade over that. We shall see.

The STI gurney flap gets me all emotional. It's so beautiful!

You should use the rings. Having said that I haven't used them (because they melted and broke apart on track) in one of my cars for about 10 years, no issues except vibrations from them not being perfectly centered.

Yeah the lift and trans jack will make it much easier, but it's still one of the many things about the 944 that make me facepalm. Plastic cam chain tensioner pads, water pump studs that turn into toothpicks over time, interference valve timing... etc. Don't get me started on the turbo... the damn crossover pipe, turbo location under the intake, downpipe bolts... I have to remind myself they are 20 year old German cars when I wrench on them. My first car was an '87 944S, and then an '89 944 Turbo which is still sitting around with leaks and undiagnosed excessive crankcase pressure, probably because I ran 18psi on 93 octane, properly tuned with good AFRs, but on stock internals

My problem was finding the correct size rings in aluminum. Only found one shady ebay vendor in my search.

But I just checked this thread again and found the right size in aluminum from 1010tires.com, so I'll pick up a set for $35 and avoid meltdown of the plastic rings at the next trackday.

lol yeah replacing the turbo on those does suck.

The problem with Aluminium hub centric rings is that they corrode and get stuck to the wheel and/or the hub/rotor. I'd rather just replace the plastic ones once a year myself up front, the rears last many years
