From time to time we take on mini Project Cars here at Vivid Racing. Â This can be a build of a customers car over time or even an employees car as they are just as into mods as anyone else. Â The new hot car on the market is the Mercedes CLA. Â Designed to compete with BMW’s 3 Series, the CLA brings Mercedes comfort and performance to an economical level. Â The CLA Class is available as a CLA250 or a AMG CLA45. Â The CLA250 features a 2.0L inline 4 cylinder turbocharged engine making 208 horsepower. Â The front wheel drive sedan has a 7 speed automated manual gearbox. Â For someone looking for a great fuel economy turbo sedan, the CLA250 is a great choice. Â Its competitor would be the BMW 328I. Â Having 240 horsepower and rear wheel drive, along with a 8 speed gearbox, its argueably a better car. Â But its big brother the CLA45 has tuners ready to pounce on building aftermarket parts for the chassis. Â The also 2.0L inline 4 cylinder turbocharged engine is all wheel drive and equipped with 355 horsepower. Â Having 50 more horsepower than a Subaru STI or Mitsubishi EVO X, its about $10,000 more expensive but makes up for it in many different aspects.
Our VR team member Dado, has himself this 2014 CLA250 as his daily driver and project car. Â Because the factory ride height and wheels are not sporty enough, these are the first things we will be changing. Â To keep cost down, comfort a priority, and a bit of handling improvement, Dado chose to go with a set of H&R Springs. Â The H&R lower the front and rear equally 1.2 inches. Â When you lower the factory shock, the stroke length is decreased but to prevent the car from bouncing, the spring rates are increased. Â This gives the car a more balanced ride while improving handling. Â Having used H&R springs on past Project Cars such as our BMW M5 E60 and BMW M3 E90, the ride of the H&R springs is very nice. Â With the lower center of gravity, the cars handling is much better. Â Since the car is front wheel drive, it would definitely benefit from a larger sway bar.
Installing the H&R springs on the Mercedes CLA250 is no different than any other car. Â As always, having the proper tools and know how are key. Â Anytime you change the springs or coilovers, you will want to get an alignment as the factory specs go out the window. Â Removing the factory springs requires pulling out the factory struts. Â We recommend starting with the fronts then doing the rears. Â The fronts are much easier being able to loosen the 3 bolts from the strut tops via the engine bay. Â The rear shock and spring setup requires you to loosen the upper shock bolt to drop the shock from the body. Â Typically this is obtained via the trunk compartment behind the lining. Â If you are doing the install yourself, you will want to rent or borrow some spring compressors. Â The front spring is under load and without spring compressors, removing the spring can cause some serious damage to you, your car, or garage. Â Remember when you are putting the struts back in to NOT overtighten the strut top bolts. Â They can easily snap so we recommend using a Torque Wrench. Â Enjoy the photos and stay tuned for our next update including the Niche 1 piece wheels.
