Castro Motorsport: Kato Racing's LS7 "E40Z06" M3 Race Car Build

[e30polak]

Friday we made a quick, but very sturdy harness bar for the M3, since Kalon had a track day on Saturday.



We also swapped wheels, tires, and had fun with the wheel color :thumbsup2:





The 275 NT05s made traction a huge problem at Big Willow on Saturday, thank God Kalon loves to drift!









Sadly I couldn't experience the M3 at the track on Saturday because we had a booth at the SoCal Vintage BMW Show, but I heard Kalon put on quite the drift show with the car!

Custom fender flares, wider wheels, 315s and a 3.15 LSD coming soon to aid the traction issues!

Amazing build! Front does looks a bit jumbled up, needs kidneys!

I really liked the idea/project to start with, but when I heard that dyno run, I was like:


Looks really clean and glad you wrapped the side-skirt with some heat-reflective tape. Probably would've melted after the first corner. lol.

ps: where did you get the boot lid (duck-tail-ish)? Looks rather fantastic overall!

Sorry for the lack of updates everyone, Forgestars should be here in a few weeks, takes 6 weeks for them to be custom made... When we get them we'll get the tires mounted and get started on the fender flares.

A factory S54 engine harness and DME are being put back into the car as well, in order to get the M3's ABS to work.

After experiencing some fuel starvation on the track, we're also going with a Radium Engineering fuel surge tank.

Hopefully we will start the cage soon as well.

Bad. Ass. Can't wait to see more of this car. Any plans for aero soon?

Yes, we absolutely plan to put aero on, Kalon needs to save up a bit more money for a proper wing though.

Here's a preliminary sketch I did of my vision for the car:

BIG UPDATE! The Forgestars are finally here! Kalon ordered 6 18x11s and 2 18x12s. We're going to see how the car does with a square set-up versus a staggered set-up on the track.

The E39 M5 3.15 ring an pinion are also being put in, along with a mild rebuild on the stock M3 diff. The longer gears will definitely help put the torque down better, as we get wheel spin at 80 in 4th gear on the freeway, with sticky 285s out back!

Radium Engineering also came on as a sponsor for a fuel surge tank and a dual AEM pump set-up to prepare us for E85 down the road. Those parts will be at the shop early next week!

Enough blabbing and onto the goods:

Incredible. Love the exhaust.
