Breaking Records with the Solo Motorsports 624HP Time Attack BMW 135i


Underneath the car, no additional panels or splitters have been added. It’s mostly just the factory pan under here.

Solo decided to try to go light, as removing weight is always preferable to adding power. With Tony F. in the car, wet, it weighs in at just around 3100lbs. One of the ways that people commonly drop weight is to drop glass. Well, not on the floor, but just to get rid of it. Oh come on, you know what I mean.

When Solo ordered these pieces from Plastics 4 Performance, they thought they were just getting simple Lexan / polycarbonate panels that would require a bunch of work to install. They were extremely pleasantly surprised when what showed up was actually custom-fit OEM replacements for the front and back windows, as well as the rear quarter windows.


What does this thing do?


Solo completely and utterly gutted the doors, but Tony F. still may need to get out of the car – even if he doesn’t want to.

A little cut and snip here and there and the factory interior door latch has been modified with this custom cable pull to allow the door to open easily. We don’t need no stinking door locks where we’re going.


The weight savings theme is continued at the back.

Solo cut out the rear bumper bar with a plasma cutter, leaving only the ends bolted to the unibody. On the left, you can see that the only remaining bits were used to hang the muffler, and, on the right, to attach the rear tow hook.
