Fitting Lowering Springs

Post by SteveSmith » Tue Jul 18, 2017 8:05 pm

Hi all,

I've been debating this since buying the car and since I've now fitted non run flat tyres the ride is so much softer that I'm not too concerned about making the ride too harsh so I'd like to get it done!

Is there anything I need to know before fitting them myself? Any special tools?

I've fitted coilovers to a couple of cars in the past so I know what I'm doing, but the Z is kind of new territory for me!

Any help would be appreciated!

Eibach pro kit. Hoping they'll drop the front 15mm and the rear 5mm.

The Eibach pro kit drop is 20/10mm front rear from non msport.

From M sport springs it is 10/0mm front - rear

The drop is noticeable

The kit I've bought states 25mm / 15mm so I was hoping for 15mm / 5mm but I'd be happy with just the 10mm front drop. It's only really the front that needs dropping slightly imo. Plus it won't effect the rear camber so I'd be pleased.

Ahh apologies the kit is different to the 35i / 35is one. Link to the one you have bought? Thanks

Very nice! Did not realise these existed. So should give you a 15mm drop up front and 5mm on the rear.

The kit for the 35is is only 10mm/0mm
