I spent my saturday installing a Kirk 4 point rollbar. Other than some mild profanity and some bloody knuckles everything went well. The fit was good but as others have brought up I wish the plates followed the contours of the chassis and the fender well better.
Thank you to those who advised me to buy longer bolts for the plates underneath the car. That helped out a lot.
A couple of questions:
1) How many feet of roll bar padding do I need to buy to cover the bar properly?
2) Do I need to worry about the tire making contact with the bolts that come through the fender well plate? It looks like it is close or perhaps I am just being anal.
The car is being hard parked till I get the padding for safety's sake. Sparco EVO's and Schroth harnesses soon to follow.
Some pics.
Question, why did you reinstall the seats ?? isn't this going to be a track car?
Less LBS = Fast
Nice. I wish I could do that, but I need to get people in my car sometimes.

Hate to tell you after you've already buttoned everything up, but I also have the Kirk bar, and you definitely need the bolts pointing to the interior.
You also don't want to put anyone in that rear seat with that bar. Think of the liability. That thing is a noggin cracker.
I kept the rear seats in place because I like the completed look and I had driven a stripped out track rat e36 M3 for 2 years and on long trips it wears on me. Maybe I am getting too old for that. Also I have plans on the future to turn her into an I-Stock race car which requires a stock-ish interior.
The fit against the headliner/roof is great. I can barely slide one of my sausage fingers underneath. I have a moonroof delete car which may fit differently than a moonroof car.
Jeff- Dont worry about the bolts. Grab a grinder and cut off the end of the bolt by the nut. It wont stick out much farther than the hex head of the bolt would have. I did this on mine and never had any contact with the tire.
Thanks Jesse! I will do that. How is the IP car coming along? When is your first track day?
A Nylok type locking nut is about twice as thick as a bolt's hex head. Since there's zero downside to pointing the bolts into the car, I can't see where pointing them outward and cutting the shanks flush with a die grinder is beneficial.
Pointing them inward also keeps the threads and nuts clean and corrosion free.

Looks great, I'm having my Kirk bar put in next week in my E46.
Car is behind schedule as expected but still looking to make Mid-Ohio April 4-6.
Absolutely, however when I installed mine years ago I did the same thing the OP did and put them in the other way and sealed it up before I realized. I hacked off the threads since I didnt feel like pulling everything out again and never had any clearance issues.
Hey guy's,
On the main hoop base plates that are angled, are the holes to be drilled pumb (straight/vert) or perpendicular (angled)?

I just ordered one but I got the optional removable horizontal and vertical bar. www.kirkracing.com
6 feet OR 9 feet of this roll bar padding?

Or any suggestions of better padding?
I only used padding on mine to hold the harnesses in the right place. My seat was ~6" forward of the main hoop so I cant see how I could ever hit it.
For some reason I thought it was a requirement to have roll bar padding even for DE...
Wrote to Kirk yesterday... they emailed me a copy of there 4-point bar installation. They said to drill at an angle on the base plates!
pm with an addy if you would like copy of install.
