Phastek in my opinion. I've had mine for a couple years.

I'm on BMR and they're great. Good company, very knowledgeable about suspension components.

I have eibach on mine...wish the drop was about 1/2 inch lower on the rear but the front sits perfect IMO. The biggest plus was that I could not tell any difference at all in ride quality from stock.

Our RST PX1 Lowering Springs are estimated to give your vehicle a 1.5" drop while the Eibach Lowering Spring Kit is estimated to give you a 1" drop. I would say to keep in mind that yes our PX1 Spring will give you the lower drop but you will notice that the vehicle feels different when driving it from stock, almost a little rougher ride.

If you care about performance, I would not alter the springs in a MRC car.

Lowering springs are great for looks, but I am the type where performance/handling gains trump looks.

MRC is calibrated for a certain roll center and spring rates and since they have software that changes on the fly, the algorithm is programmed for that.

There are multiple reports on the forum from members who have done this and seen the rear-end get upset on track.

Good point TRZ06. but, you only know half the info deterring people away and giving bad advice from not knowing all the facts is not appreciated..


.. Also if you switch tires as well you need to recalibrate I went from 20s to 19s. not a big deal to do my dealer calibrated for free.. of course I take the mechanic golfing lol.





the gap in front to me looks worse than the rear.. a combo of 1 inch in front and 3/4 in back would be nice! I think any lower it would be a paint to get around!

1.5”’ drop compared to a 2017 or a 2018 and above?

Also what is the spring rate on your springs compared to the stock rate?

Guys these springs from Phastek do not seem to be meant for ZL1, the rep told me the rates and they are less than the SS

PX1 Springs
Front - 120 lb/in
Rear - 430 lb/in

Higher rate springs do not equate to better handling
