Lowering a ZT 160

Rigginsuk · 23rd July 2015, 10:04

I'm considering lowering my ZT 30-35mm. I thought it would improve the over all look as well as improve its vertical centre of gravity. Since most car manufacturers standard suspension can be lowered about an inch before it starts to hurt the normal handling of the car I figured that's as low as I would go.
There was an optional extra when the car was built of having MG Sports Suspension. I'm not sure if mine had this option. I was under the impression that all of the Z's had uprated suspension. With that in mind, would lowering it 30mm actually damage the handling rather than the opposite?
I found some lowering springs for a Rover 75. I've never ridden in a Rover 75 before so I'm not able to compare the ride between a 75 and a ZT. I had a ZS 120 for quite some time and the ride was much stiffer. I know the ZS had uprated suspension over the Rover 45.
The lowering springs are on nicedeals.co.uk part number FKRR009. Rover 75 (RJ) Lowering Spring Kit. The other thing is they're really cheap in comparison to the ZT lowering springs I found on Fleabay.

After all of that (I do apologise, I get very enthusiastic when talking about these cars) the questions are:
Does the ZT's have updated suspension over a Rover 75?
Is it a good or bad idea to lower a ZT?
Have I found a really good deal on lowering springs or am I totally off the mark?

Thank you guys / gals for taking the time to decipher my ramblings.

Just be aware that the ZT is already 20mm lower than a 75, so if you fit 75 lowering springs, you may not end up any different to what you have already!

Fitted Eibach Pro lowering springs to mine, down 30mm so probably, as Mark says, it's about what a ZT is now.

Waiting on delivery of a set of lower springs for my 75, going to drop 40 front 30 rear. Should aid looks. I noticed a large disparity between lowering springs for 75's and ZT's. No idea why. Keep an eye out for springs listed as 'progressive'. They should limit the hard ride and keep it comfy, sort of.....

I've got motobuild lowering springs on mine. Gives a 25mm drop over the ZT springs. Handling round corners definately improved but now that the springs have settled in theyre definitely more rough over speed bumps and bumps in the road.

Thanks guys for the feedback. Rather than get the 75 springs I've found some ZT springs for £160. They claim to lower it by 25mm which will be just fine. Probably due to owning a ZS which has quite firm suspension. The ZT, though very comfortable, is a very soft ride. I miss the firmness but wouldn't really like it as firm as the ZS was. The springs I found don't seem to have a brand name which is a little worrisome. I see a couple of you have brands like Eibach Pro and Motobuild. I assume these are considered quality springs. However shouldn't all lowering springs sold here in the UK follow a set standard? I wouldn't normally consider a non branded item such as this but the price is half that of branded springs. Normally for my car it's quality over price but I have a lot I want to do to her and a budget I need to try and keep to.
