RWD FBO M235i 1/4 mile 11.82 Updated with video

So brought my m235i out to the track this past weekend and was really happy with the results. Best run was 11.82 at 117.6 mph. Mods are intercooler, charge pipe, intake, catless downpipe, dorch stage 2 hpfp, flex fuel kit and bootmod3 stage 2 + flex fuel tune running e65 ( best the gas station had ) on an 8 speed auto. Managed to play around with some things on bootmod3 turning down power a bit in 1st gear. started at 25 percent less and worked my way to 10 and that seemed good on my street tires. But here are some time slips. Im always on the left lane. Will add videos once i get em in .

No weight reduction. Maybe next time i'll consider removing some weight. Got some tires in the works so i'll need a different set of wheels.

Great runs!

The track prep must have been insane because low to 1.8 60 foots with a RWD car on street tires is bonkers, admittedly, borderline unbelievable based on my 20 years of drag racing experience.

Curious, what tires are these?

Impressive to say the least.

It was mid 60s the day you raced. Go out there on a cool/crisp 40-50 degree day and you'll likely see 119-120mph trap speeds. ET likely won't change because traction will suffer with the colder track surface.

For sure! Going to try some weight reduction and try to get some VP Racing c/x85 to see what happens.
