Greetings!

 

I came across the suggestion to switch to Poly bump stops given their superior geometry. I wonder if such a simple and small change can lead to any noticeable improvement in ride quality. I am currently running on new standard rubber cones and 12 inch wheels running 165/60 R12 Dunlop rubber, but find the ride quality over harsh London roads to be quite...well...harsh.

 

I will gladly purchase any modifications to improve the ride. My shortlist so far includes:

 

1) Poly Bump stop (assuming forum feedback is good)

2) KYB Gas-adjust struts

 

Any other suggestions welcome!

They won't really change a thing for general driving as they don't get touched. It is only for extreme end of travel.

Poly bump stops wont do a thing. If the suspension ever reaches the bump stop you would be better of with rubber ones.

 

Only advantage is the poly ones would last longer.

 

Its a min! They tend to have a harsh ride.

I should have clarified that this was for the crash craters on our roads and not daily road imperfections

I wouldn't fit anything Poly, it's too hard and the wrong material.

 

If you are looking for a better bump stop, that is less harsh, fit these;-

They are so good in fact that you won't even know you've touched the Bump Stop when they are called in to 'action'.

 

These fit to the top arm, on the shocker bolt (you'll need to drill the hole bigger in the mounting bracket) and you'll need to remove the existing bump stop of course.

The best way to make a classic Mini more bump-compliant is to do the following:
Fot top-quality rubber spring cones, raise the ride height by around 1/2" all round by using Hi-Los, fir adjustable dampers set fairly soft and put the tyre pressures at no higher than 28 psi all round.
If it is still not sufficiently bump-compliant it would be best to buy a bigger car with large wheels and high-profile tyres (a Land-Rover Discovery is great on such bumps).

If you know your stuff and want to fine tune something to suit there is plenty of choice

Clearly your mini isn't low enough if you have bump stops  :lol:

 

Maybe new seats?  :whistling:

So these can be fitted to dry cars too with the small modification to the bracket? I had been wondering about them
