1st Full track day with my GLA45
Just went out to a track day yesterday with my GLA. I didn't know what to expect as my last car was a C63 tuned and on KW V3's.
My GLA only has Weistec Down Pipe.
First thing to note no overheating or limp mode even in MANUAL mode. We drove in 20 minute sessions full out on the 2.4 km circuit. Average speed was 98 kms with top sped of 166 kms. Best lap time 1:23 Same track in my C63 my best lap time was 1:22 with a 188 top speed. So you can see just how much better this chassis is. I can get the power on so early in the corners and the transmission is amazing. The GLA understeers pretty bad and shredded it's front tires. Also body roll was more than expected, my plastic fenders are now shaved for a custom fit thanks to body roll. (I do have 20mm spacers) Now all we ned is KW to make suspension for this thing and we will have a great car.
In my C63 I had to use sport traction and sport transmission or it would overheat and go into limp mode.
Couple of pictures of your car, hope you don't mind me taking it.

KW just sent me their latest application guide and we have part numbers for KW coilovers for the GLA: Variant 1 and Variant 3 for the GLA 250 and Variant 3 for the GLA45.
Send me an email (nmahzari@hgmotorsports.com) and I can work out pricing for you if you are interested.

I went 20mm and could of gone a bit wider. Normal daily driving NO RUBBING at all even with 3 people in the car. On the track there was some rubbing in the rear but just the plastic fender trim. That melted away and now it's a custom fit! ha ha. I wouldn't go any less then 20mm. I have KW V3's on order so I may need to adjust this once the car is lowered. I will see. Good luck!
