Awesome to see another performance track car build. Wish you were closer to chicago to go to some track days with! I'm usually at the track by myself :(

Are you managing to get even wear at the front with only -1.9 degrees camber? What tires are you using for the track?

Tires wear perfectly even. It's typically toe that kills tires, not camber.

Currently the Firestones have been both track & street tires. Eventually a dedicated track set will be obtained. They have more than enough grip and they hold up to abuse (heat) well.

Thank you!



I am entertaining some events out in Ohio this year, not sure if you typically drive out that far.



Will have some more updates in the coming weeks!
I'll be at mid ohio for memorial day with chin motorsports!

Sorry should have been more clear, meant at the track. Just surprised to see you're only running -1.9 degrees camber in the front. Most macpherson strut cars I know (including my primary track car) are running -2.5 to -3.5 degrees to get even wear across the tires (200tw or rcomps).

I don't normally track the GTI though, so could be a platform-specific thing.

Ah I see what you're asking. Currently with the superpro ball joints that's about as high as I can go. I would be able to go more, but for some reason the left side of the car is off by almost 0.4, so in an ideal situation I'd be able to get close to -2.5, but when maxing out both sides it turns out to be uneven.

If I have to suck it up and run camber plates I will, but for the time being these are working well.

I'll be at mid ohio for memorial day with chin motorsports!
Awesome, I will definitely check that out. SCCA is running a few Track Night's more local to me, but mid-ohio is always a track I wanted to get under my belt, so I might take you up on that.

Big update!

After doing more research on the HPA vs IE intake manifold, and talking with both companies, it appears IE has a slight design edge over HPA as they have flow tested velocity stacks. HPA's are equal distribution, but runner length, diameters, and resonance tuning are all factors that IE took into account during R&D to fully optimize power gains for any turbo (including the KO4), which appears to be something HPA overlooked. So I'll be going with the IE manifold now! (plus the manifold is on sale which pretty much sealed the deal)

Also, the KO4, manifold, and all remaining suspension components have been ordered!

I also ordered a carbon spoiler through Revozsport, which should hopefully be here in the next week or two. I decided I liked the look of the Revo more over the OSIR, but will stick with OSIR for the diffusers/side skirts.

The only remaining components on the table are the BBK, TyrolSport radiator, the remaining body work, and some interior tid bits. I should hopefully be able to pick those up by the end of the month. Stay tuned!

Where do you autocross? I'm looking to get into it for the first time ever this summer. I'll be doing it with FCSCC in Stratford.

We should meet up sometime and talk cars. I don't know of many other mk6 Gti's around.

I originally started Auto X with FCSCC (I still have their "Doctor of Pylons" award from when I did their AutoX for new drivers school) but their events are pretty far from me. I much prefer going to the CART events (Connecticut Autocross Rally Team). They're more in central CT versus Fairfield county. They have a track day at Thompson on May 5th that I am going to try to be there for.

I'm in Rocky Hill; I frequent the Berlin Turnpike on the weekends, should definitely meet up! Car is gonna be under the knife for the next few weeks, but once the car is settled and dialed in most definitely.

Ah ok! I was going to start with CART but then a friend of a friend suggested FCSCC because they have bigger lots for it. CART does most of their events in Hartford, right? I looked into them briefly.

I've got family in Wethersfield and in Rocky Hill (off Rt 3 near Westside Super Market) and I am currently in Middletown so I know the area pretty well.

I check out the Berlin Turnpike pretty often during the summer months so i'll definitely keep my eyes peeled for another mk6.

Speaking of the pike... what are the most popular times for meet ups now? They used to go pretty late and me and some buddies would show up for around 10pm but seems like the cops have really cracked down on it all. Past summer or 2 have seemed dead on the Berlin Turnpike... at least late night.

They use 2 lots, the bigger of the two (the south lot I believe?) they only use maybe 3 or 4 times a season. The CART lot (1-17 Pequot Street Hartford CT 06120, if you google map it you'll see the skid marks from the satellite image that's the lot) its bigger than the north lot but not quite as big as the south lot. Either way you're only looking at ~40 second run times no matter where you go. Also just in terms of the people I enjoy the CART folks a lot more--they're a more laid back crowd imo.

The pike has calmed down a bit for sure, but when it's nice out there's still a good crowd... they just go to route 9 to race instead of doing it on the actual pike (which is probably why police haven't really bothered us). Out of all the nights I've stayed there late last summer we only got kicked out once.

And you know what's funny is last summer I did street race a CSG MK6 on the pike that I believe he said was Revo stage 1 at the time. Who knows we might've met and not realized it haha. We both had passengers, we went down pretty far on the pike almost into Meriden.

The focal point of this car since I got it has been the suspension and drivetrain in order to accomplish one thing: to eliminate or minimize the weaknesses of FWD. As evidenced by the new Civic Type R (and ClubSport S), a properly setup FWD car can be a serious contender. I have experimented with multiple suspension setups that I will be happy to share with you all.
I am curious why you didn't seek out a Golf R as a starting point. I am considering making more engine modifications to my GTI and wonder if I will be disappointed without AWD. What was your thought process on that?

I didn't go for the R because I knew I wasn't looking for a crazy amount of power from this car (which would be pointless for that very reason you mention). The KO4 allows you to gain a healthy bump in power, but without overpowering the chassis completely. With proper suspension and drivetrain modifications you can still maintain that well balanced, nimble, all around fun car that the GTI was meant to be.

The price difference between the models was also fairly large (over $10,000 at the time), which played a factor as well.
