Ever wonder why one of the Type R chassis modifications Honda did was to increase the rear wheelhouse thickness? This is a common problem to have on non-Type R DC2 chassis that see a lot of spirited track driving. The rear roof rail and pillar will also start to show signs of stress via cracks and ripples. The amount of stress the rear body experiences is pretty amazing.




I bet non-Type R enthusiasts will find it surprising that more is behind the DC2 Type R then the red emblems, decals, red valve cover and big rear wing... Honda did a lot to make it a competitive FIA approved chassis.

I bought a type r rear quarter panel thinking the only difference was the holes for the moldings. It took some extra work to get it on the car and fit up correct for the guy that did the work.

The key is to cut a Type R in half and take EVERYTHING behind the rear seats. It's the only way to get the entire package. Either that or install a well engineering roll cage that strengths all those areas, or do both.

I always found it funny that you can find JDM front clips EVERYWHERE but never a rear clips. Who care's about the Type R motor, IMO it's the most underwhelming part of the car. That and the transmission. Pro touring cars would eat Type R's up for lunch because the motor/drivetrain but thankfully the chassis was outstanding and could make for the disadvantage.

I figured that was the case causing the cracks, just have never seen it before first hand or even in pictures. Just heard stories about it potentially happening.

Yup, agree. Motor is kind of weak, but I blame a lot of it on the factory tune. My car unfortunately has the p73 ecu at the moment so vtec doesn't engage till 6k rpm. Also doesn't help when you have a 4.4 final drive either. I'm pretty much dead mid corner with the car as it has no pickup from 5-6k rpm. It pulls fine high end. I think if I ever crash my current ITR on track I may end up picking up a DC5/RSX chassis and work with that. Chassis is very rigid, and many parts avail to work around the faulted suspension geometry. I find it kind of interesting that the fastest Integra around Tsukuba currently is a DC5 with a stock K20a. Ran 58's last year, and this year running a built K24. Been following the shop for awhile. Car is very impressive. https://www.youtube.com/watch?v=7XrO238nszw

I honestly haven't looked yet. but should be fine? haha

upcoming track days :
April buttonwillow
Type R Expo West!

QFT

I think I spoke too soon, West isn't going to happen. My girl and I have something planned, and I bought that s2000. I am gonna post some updates on the HFF event at LVMS, but integra is currently in retirement for a 2nd time. This build may morph into s2000 related stuff.

I wouldn't mind picking up an S100...where abouts did you locate that one?

Thanks, I appreciate it!

I found it bnib on Craigslist.

I got those too unfortunately. maybe ill snap a photo.

Retirement? Uh oh...

So that wheelhouse is essentially the rear wheel well? Usually is black, but then over time it gets nasty to the point where it needs to be repainted. I wanna say someone on the old forums used POR15 in that area.
