    Purchased used suspension for my car. Will I be OK? 10th Aug 18 at 6:00 PM
    Hi

    I recently found out my 56 reg Mazda RZ8 PZ does not come with the OEM suspension but instead the standard dampers and springs. To avoid any insurance issues and to have the benefit of the PZ suspension I approahed Mazda main dealer and for all four springs and shocks it's a staggering 1800 plus VAT. I came across a used set on Ebay for 250 and it came off a RX8 PZ that did around 65k miles. It looks in decent condition with no real corrosion so should I be ok? It kit is already assembled with all fixings and my mechanic is charging 200 including VAT to remove existing suspension and fit. Does this sound reasonable?

    Who knows the 250 set could need replacing very soon after. Then you will have wasted 450 and still need new suspension.

    I was once quoted around 400 to change both front shock absorbers on a nissan micra from 2 garages, so 200 for the whole lot to be changed sounds reasonable. The only thing i'd be worried about is that the set your fitting has already done 65k miles and could still be quite heavily worn despite how it looks on the outside.

    Just leave the current suspension as it is. It won't be long before you've written the car off.

    "To avoid any insurance issues" - are you assuming as it has not got the standard PZ suspension but has standard, it will be an insurance issue? Is or was there an option when the car was new to not to have the PZ suspension?

    I have seen on many cars, when new, that have a sports suspension, you can, at no cost revert to normal suspension as it gives that better ride. Maybe the original owner did that? If thats the case, perfectly legit.

    As this is a money saving forum the advice is to keep the suspension that you already have on the car and enjoy the extra comfort and sport suspensions are not designed for comfort but for racing so a normal suspension would affect handling.

    But if I was in a sports car forum I would say what the heck, I am going to shine these springs till they look new and drive like starsky and hutch.

    If the suspension you've got is OK keep it. At 65,000 miles the shock absorbers of the second hand ones you've found will be nearing end of life.

    Well, whenever you buy a used car you are buying a used suspension, so there is nothing inherently bad about it.


    However, 65k is quite a high mileage and if the sports suspension has been ridden hard, then it may be past its best and so buying it won't have been a good financial decision if you need to replace is within 12 months.


    200 in mechanics fees seems very reasonable.

    Personally I wouldn't entertain fitting some used shocks that are likely to be performing significantly worse than they should. It could be worth a little research as to who makes the OEM parts and if they are available elsewhere...

    On my current car the Saab stamped suspension is made by Sachs, you can get an identical part for half the price by buying from them.

    Springs are designed by Prodrive and Eibach. The shocks are Bilstein. Assuming the shocks and springs are in good order at 65k miles, shouldn't they still deliver the same driving performance as brand new ones?

    After 65k miles the springs should be fine however the shocks will have lost a fair bit of damping ability and will not be performing like when they were new.

    Check the rear springs for wear at the top. The end of the coil wears away at the next coil down and they break at that point. If you look at the spring the wear will be obvious.

    Amazingly, my car has done double that mileage, is still on the original springs and shock absorbers and they are all still performing well.

    And, of course, when you go to check out a used car one of the things you do is push on each corner to check the shocks.


    Nobody is saying that they will be pooped, but rather that they may be...

    I thought that on my Mondeo. 133,000 miles, shocks not leaking, car still passing MOT with them, following the wife in the car there was no signs of the wheels bouncing on bumps. I decided to change them after taking the caravan out for the first time in a couple of years and thinking that I didn't remember it handling as it did.

    Couldn't believe the shocks I thought weren't too bad were actually well tired compared to the new ones. The new ones you couldn't push in by hand, the old ones you had to pull out by hand to extend them to their full travel and they could be pushed in and out with ease. After I changed them I happened to be at a mate's garage and he had a Mondeo on his forecourt for sale with similar mileage. Doing bounce tests with the two of them it was startling and the car handles a whole lot better.

    I think if you took a shock off your car and compared it to a new one you'd be quite surprised as well.

    +1 for the last post.

    Shocks performance will gradually reduce over time, not an issue for many people but if you have a sports car or want the handling to be as good as possible they do need replacing from time to time.

    It's interesting to see posts from people who are unsure if replacing their shocks is worth it and are then amazed by the difference, this is quite regular on another forum I frequent.
