Bolt In Half Cage / Roll Bar & Rear Seat Delete Available :)




Pretty sure you're already on a lot of tracks
And
You would be adding weight
So are you adding just for safety? Almost sounds like a dumb question but I'm actually curious
P.S. paint it red




3909 lbs before
Rollbar is +50lbs
- removed OEM F/R seats 200lbs
- removed rear airbags, rear seatbelts and assorted trim etc 30lbs
- removed OEM battery and assorted stuff 74lbs
- removed fender liners 24lbs
- removed dust and dirt and gravel and track clag 1lb
+ install Sparco Evo 2 seats with sliders and Planted brackets 70lbs
+ install Schroth 6-point harnesses 12lbs
+ install VoltPhreaks battery 7lbs
3719lbs after
You were saying?

The Best of Mercedes & AMG




Pros: Better brake and engine cooling in front. In the rear I get another inch of tire/rim possibly if I can get the offset right (was already rubbing clear through the rear fender liners and the front as well). Also much easier access to adj suspension components I have to get to.
Cons: unprotected brake and fuel lines (will cover with gorilla tape maybe), there are some sharp frame edges that the liner was probably protecting my tire from on suspension compression (will have to grind down).




Come on now...
Sidebar: Was browsing the IG when Studio RSR posted something for BMW. I commented about a harness bar for sedans. The guy John said they’d like to develop something for sedans but need a car...so if any of our sedan brothers are in SoCal, contact those guys.




Let me first say that it dropped in perfectly. Fit and finish are impeccable.
BUT.... this is not really a rollbar. At least not an effective one as designed. Think of this as a super pro-looking harness bar. The reason is problematic mounting points.
Here is the bar in the car. Pretty sweet looking.
First issue. Front mounting point is on top of some sort of super hard welded plate (had to use up two concrete drill bits just to get through) that bridges a channel. This point is probably not so bad, but there’s space underneath the plate, and then there’s the raised bit of the floor that made up the thigh support for the back bench. I don’t think this area would survive a rollover, and those legs would slip off the bump anyway.
Here are the rear mounting points. These are just dangerous IMO. The plates on either side slide right in place, and you can even use the OE 10.9 seatback hardware bolts. Now look at how the bar terminates on the plate. I took two angles to show that there’s nothing but air under the rear bar ends. In the event of a rollover, 100% that those plates break. There’s literally no support.
So, while I get that it was advertised as a drop-in cage and was going to have some compromises, I’m a little disappointed that it fails in such a critical area. Will be giving this feedback to the Studio RSR guys, as I think the design could be modified to address these issues while still remaining “bolt-in”. While the bar material and construction might be to NASA spec, the mounting points probably won’t even pass a cursory inspection. Maybe I can modify this bar to be better secured on the rear points.
Right now, this design, I couldn’t recommend. Let’s see if it’s something that can be fixed...

Studio RSR Rollbar
Sparco Evo II Seats
Planted base and side mount brackets
Schroth 6-point harnesses with other bits
Looks pretty good in there I think




I should add that I sat in the OE seats with the seat bottom all the way down in back and up in front. So the additional 3” of adjustment will get the seat 1” off the floor if you want.

Thanks guys. It’s not perfect but will get there in time.
