MX5 NC Front Drivers Spring higher than passengers

Technical Area Steering & Suspension

Hi All,

I recently had the two front springs changed out with replacement standard springs. (I know I know, it’s my wife’s car and she liked it as it was).

When it was first fitted I remember thinking both sides looked high (the drivers side maybe more so) the passenger side settled down after a week (and I heard a slight poing noise when reversing off a uphill parking space) but the drivers side didn’t and was about 1.5cm higher.

So I left it for 2 more weeks and took it back to the garage suspecting “twisted” bush. But they loosened off those bolts on both sides and then tightened them up with the car on the ground. It made no difference.

I have taken it on a 900 mile roadtrip which would have given it a good chance of bedding in, with lots of country lands and steering angles but the drivers side is still noticeably higher.

Any idea what it is, as the garage is pretty adamant these can only go back in one way. They mentioned when rechecking that there was some oil on the damper rod (both side) but to me that doesn’t explain why one side is more 4x4 than factory.

Any ideas ?

Hey,

Can you tell us more about the model you have?

It’s a 2007 Mazda MX-5 1.8 NC (standard suspension) :+1:

Hard to tell which one of your springs is not behaving correctly, because most cars produced between 2006 and 2009 came out of the factory looking like a 4x4. Only those with the bilstein shocks didn’t ride high.

On our 2007 PRHT, the gap from the centre of the wheel (badge) to the lower edge of the bodywork/fender
was 355mm AFTER lowering on 30mm Eibach springs.

Before it was 375mm on each wheel front and back.

The new, lowered, rear-wheel gap is 340mm

Thanks but the question is more, the springs on the front have both been replaced with standard springs but the front drivers is sitting higher.

Any ideas why? Feels like something has been bolted back together wrong, but what?
