Hi, I'm new to the forum so pardon if I don't know the proper decorum for posting a question but I couldn't find my particular question anywhere.

For some background, I have a 2014 CLA 200 which I recently purchased. I live in Colombia, South America. The roads here aren't the best but the biggest bane of my existence are the non uniform "home-made" speed bumps I come across regularly. Usually taking them SUPER slow or at an angle helps but some are just ridiculous. I've gotten by barely scraping on most but I have bottomed out twice and its not a good feeling. No damage so far, since it was at a snails pace but I worry for the longevity of the car if this continues.

Long story long, what options besides getting a different car do I have to increase the ride height of the car either variably (raising and lowering at will) or fixed (leaving it 1-2 inches higher permanently)?

Hate to say it but the GLA is a better fit for your particular roads ...
Only so much you can do with existing springs and shocks ... the taller springs and longer shocks from say the GLA parts bin may be a start but the alignment to compensate would be an interesting exercise, and that cost and effort almost hints at a trade in path towards a small suv

Not a fan of SUV's at all. Honestly this car is perfect aside from this one very annoying issue. The difference between the GLA and the CLA is about 1.7 inches. If I could raise it up an inch i think my problems would be solved. However you are correct, it might not be cost effective.

Any ideas as to alternatives, i really don't want to get rid of this car.

haha I want to look into some air shocks, I have no idea what would be needed to make that kind of conversion. In theory at least it would solve all the issues i have. Is there a thread on air shocks? I'm gonna try to find one on here but if you know of a specific one I should check out I'd appreciate it.

I know my fathers 2012 CLS has this system. Maybe you could get someone to retrofit it on your car. Tho I cant imagine the cost. Maybe if you find a wrecked CLS and get the suspension parts and code it on one of the blank buttons haha

I had the same problem, to fix it I had to change my tire size from 225/40/18 to 225/45/18. This raised my ride height significantly without any rubbing issues. By removing battery terminals and putting them back on the CLA rebooted and recalibrated tire rotation and speed. I am also considering strut spacers.

Going to 225/45 from 225/40 does give about +11mm (almost half inch) ride height increase
Presuming the upper half of the tire does not contact suspension points this would be a first move to consider
The speedo reading error is about 3.53% low

Thats super interesting, I've got 17inch rims so I'll have to see if the increase would be enough but this at least sounds like a much easier fix than switching out the entire suspension. Do you think switching to a 225/50/R17 would do the trick? How difficult was the recalibration of the speedo? Would 225/50 even fit?

oh ... you have 17 rims
so i presume stock is 225/45-17 so 225/50-17 would be ~11mm extra ride height and -3.43% speed error
though the main issue would be to make sure the top of the tire misses the suspension points

was this automatic? or was there a cal process?
This was automatic. I bought an app to measure the speed of the car when in motion compared to the dashboard, the car was about 2-3 km/h more than the app. At battery change I realized that the dashboard had normalized and was in sync with the phone app.

Fascinating ... not sure how a system reboot can recognize a tire rolling diameter change?
Unless it reacquires and triangulates satellites as a reference etc

It really amazed me as it does to you. All that matters now is that I can stick to road speed limits without worry of over-speeding, especially when on cruze mode.

What model year is your car? Do you have GPS on it?

enforcement folks usually give 4~5% error windows so you should be ok
fun part is to hack a bud's car to read -10 all the time ... heh heh heh ;-)
