Hello !
First post, but been reading a lot of stuff here!

I need your help and inputs

I will get my C450 in a few weeks. I go to the track few times per year.
I lease the car and I want to replace as soon as I will get the car few elements. I do not want to make it a track car, but just more elegant + have some benefits on the track.

Your comments / recommendations would be greatly appreciated !!

1) Tires dimension : I choose the 19'' wheels. I will get the Michelin PSS, non-run flat. I will put back the Pirellis when I return the car. As for the size, how big can I go ? 235 in the front and 265 in the rear or can I go bigger ? anyone else did it or just everyne stick with original size ?

2) Wheel spacer : anyone installed wheel spacers ? there are many mm options, any recommendation that looks just good and not too wide ? pictures ?

3) Springs : I was thinking of getting installed the H&R, a small clean drop.

4) Brake pads : I see no manufacturer doing performance brake pads yet ?!


Thanks for your inputs !

Springs: KW will bring a coilover spring kit soon, and coilovers later this year!

It funny that you say this because today I got confirmation from KW head office that for the moment, their R&D team is not working on this and they have no ETA for the moment.

It looks like I will have to try all this myself first !

Maybe there is a difference between USA and Europe, but i received this mail last week:


Sehr geehrter Herr,

Vielen Dank für Ihre Anfrage und dem damit verbunden Interesse an unseren Produkten.

In absehbarer Zeit wird ein höhenverstellbarer KW Gewindefedernsatz für Ihr Fahrzeug verfügbar sein.
Ein KW Gewindefahrwerk ist geplant, wird allerdings erst ab Herbst verfügbar sein.

Ich hoffe wir konnten Ihnen mit dieser Stellungnahme weiterhelfen und verbleiben,

I cannot comment on mods as I don't use my C450 for track-days, but did decide to take it once on a rainy winter track-day. I was very surprised how well it did, especially the brakes. The S+ mode is quite hilarious and makes it areal event to drive the car.

Last week I also took the car on a snow/ice track. I had to play around a bit with all the settings. S+ only seems the drive the rear wheels, in comfort mode the throttle response is too slow, etc. S offered the sweet spot. All in all the car is doing too much but once figure it out it's really good.

As for modding the car, I long ago concluded that a car is either made for the road or the track. You could put some harder pads and different fluid etc, but you cannot hide the excess weight over say a Porsche. I also could not put up with the squealing of race pads when driving on the road. So personally I think it makes more sense to enjoy your C450 for the road and rent a car for track days.

In any case, you will love you car. It's one of the best all rounders I have ever driven.

For sure it will never be a good track car, but still I enjoy tracking few times a year.

and looking for OBD2 reader bluetooth to connect to my phone/track application.
OBD2 ELM327 Bluetooth will work ?

thanks

Did you end up changing your tires and how pilot Super Sports working out for you? Thank you.

I might chime in. I did replace the tires for MPSS and they are a vast improvement. I also tracked the cat with the pirelli. Can't wait for spring to track the car with the MPSS...

highly recommend the switch as MPSS is the top choice of max performance tires. You cannot be disappointed.
