M4GTS Track Build

MRakete · 12-30-2019, 07:13 AM

If you want a great rack car... Just get a Porsche GT car. GTS can't compete with a GT3. I speak from experience.

Heres an update. We are pulling the differential carrier as I write this so we can install the Drexler unit. For those of you that don't know, the Drexler differential is the GT4 differential. It will completely eliminate the OEM differential with the actuator and the power will now be sent through a motorsport ramp style differential. The reason we are doing this is because the OEM electronic diff has a calibration that is not suitable for the track. The Drexler diff is the most exciting mod on the car as we expect it to completely change the dynamic of the car and help us to gain seconds on track.

We are a Drexler dealer. Please contact us if you are interested in installing this differential. The process to install the differential includes machining the rear end so this is not a direct swap.

Below are some other parts that will be going on the car soon.

awesome parts. are the moton/ast plates directly compatible with the shocks or did you have to customize?

We are going to use the GTS splitter for now. We have brake ducts that fit directly into the GTS splitter openings.

We had shims made that adapt the Moton plates to the Ohlins.

OEM Differential and muffler out.

Love the GT4 wheels!

Flossmann carbon fiber DTM style trunk arrived from Germany. Weighs just under 9lbs!

Flossmann parts available through YMS.

YMS · 01-28-2020, 01:11 AM

Carbon fenders and wing end plates

YMS · 01-29-2020, 01:33 AM

We spent a whole day just getting the fitment of the fenders how we want before they are sent for paint. The pictures below are not the final fitment but getting close.

Nice

What was the ballpark cost on those GT4 brake duct backing plates? They look beautiful.

edit: https://www.apmotorsport.co.uk/produ...bon-brake-duct. ~$1600. Think I'll just mig together a one-off piece

Agreed. Stock GTS on a track can't compete when compared to the Porsche GTs.

Also BMW carbon ceramic brakes are absolute shit.

Hahaha I took the previous tune off. It was causing a lot of drive-ability problems and eventually it just became annoying.

Thanks for not making that poping sounds dumbest thing ever

You should have just bought a gt4 and a wrecked regular m4, stuck the vin plates on the gt4 and had it titled in florida. They'd title a manatee down here if you put a vin on it.

Who's on first · 02-11-2020, 02:46 PM

So, what's this cost... about $5,250 in parts and labor extra?
