I'm happy with the product, it was delivered as promised. It performs well on the SL55, only recommendation is to develop the torsion bar kit for the ABC suspension cars. The car performs good in straight line but around corners you do miss the anti-sway bar.
Perfect for the track, a little tight for gravel rally but we’re tweaking the adjustments after the next race.
Also the spring on the rear shocks is impossible to adjust if it’s not down a half inch before installation.
Overall very happy with the coilovers. I was able to remove the Audi air suspension and replace it with these coilovers. They fit well and seem well made. Ask for the softest ride possible and they feel really good on the street, even the wife & kids are happy!
Only downside is the helper springs basically bottom out under the weight of the car and don't seem to do anything since they are fully compressed.
The product I received, I am very happy with. The only issue that I have an I have to assume that is in large part due to covid - 19 is the time it took to receive the order. It took about a month to get the order in due to delays on the color that I picked for the suspension (2-week delay for the red color) and then another 2 weeks for the order to be shipped. I was never informed of the delay until I reached out to the company myself to figure out what was going on with my order. If you need to contact them about your order, I'd highly suggest that you follow their page on Facebook and message them on there. They're pretty response that way.
