i dont know if is the problem or it is normal for mini. i have 05 MCS some time my car shake and bumpy when i cruse on highway. and make me feel i wanna throw up. and more notice on uneven road surface. so the question is that stock suspension is bumpy?

 

if is normal. what should i do to make it comfort? like change the spring or change the shock?

 

Stock suspension is stiff, but it sounds like your's is rough. How long have you had your car? Has it changed feel? How many miles are on it? Are you still under warranty? You could change springs but it might be the struts. You could do springs and struts or coilovers but depending on which you go with you could be out $$$ and have a harsher ride.

Drive someone else's car, or a dealer car, and find out if it's the car or you.

 

as i said i have 05 mini and the odo now is around 19000miles, before i have a tie steering wheel and i send to the dealer to adjusted. i feel the problem starts after the winter time when i put my snow tires on it, then i change back to s-lite 2 months ago then on and on..

 

stiffer = bumpy? softer = comfort?

 

Hmmm, probably not the springs or struts, you may just need an alignment to make everything work correctly.

Or something could have been knocked out of place during the winter. Either way, 19000mi and 2 years old = take it to the dealer. My advice is get them to fix as many things as you can while you're under warranty. Once 36000 rolls around you'll wish you did.

Good luck-

Koni FSDs!!!

You keep the stock springs. It'll feel like a whole different car.

Give Scott a call at Central Coast Coopers.

 

If your "summer" set-up is S-lites, then I'm betting that your winter tires are higher sidewall profile on smaller wheels, the combination of which will be lighter weight and softer ride (the winter tires are likely non-runflat, too). Switching from softer, higher profile tires of lighter wheels to low-profile runflats on HEAVY wheels will GREATLY affect the ride. I don't know if you have some other suspension issue(s), but the tire/wheel swap would make a big difference alone.

 

These questions would be easier to answer if lanevomr's posts were in English.

so what language were you read as?

 

you are right about my wheel size. and i also have 22mm rear sway. will that affect the bumpy issue?

 

Tire pressure? (I run 30 psi)

Blown strut? (look for oil around the strut body and where the shaft comes out of the body)

 

In a word. Yes. Put back in the stock bar.

If you want a smoother ride switch to 16" wheels and use conventional tires, not runflats. Over inflated tires as mitchman indicated would also make for a firmer ride.

Have you changed the springs or lowered the ride height? If you have put it back to stock. Someone else mentioned Koni FSD shocks and that is an excellant suggestion when combined with the stock springs.

The MINI is a sporty hatchback and sporty cars have stiff suspension, it is the nature of the beast. If you manage to make it ride like a Camray you will destroy the handling that makes a MINI a MINI.

 

good point i got you

 

Things you can do (some of which has been mentioned already):
1) Change to non-runflat tires
2) Put in some Koni FSD struts
3) Use a smaller rear sway bar (I swapped my 22mm on medium for a 19mm on soft, and it made a huge difference)
4) Install some Ireland fixed camber plates (which have a thicker bushing(?))...

I've done all of this (plus JCW springs), and the improvement in ride quality was tremendous. It still is stiff, but no longer thrashes over large bumps and potholes as bad. And this is with 18" wheels and 35 series tires...

 

just another question, is there rain grooves in the highway you are on? if so and you have sport tires they will track in the grooves alittle giving a bumpy side to side feel.

 

Translation, please?

 

Don't be a douche.

Not everyone's first language is English, but we know what he means.

Take it easy.

 

The great linguist Noam Chompsky suggested that language, for the most part, is contextual.

The guy has a ride problem, I get it.

...broken lower control arm bushing? I'm reaching since all of the above replys are more than likely a cause in part or whole.

 

Ok, only because I am a fan of the word douche, and despite being difficult am not one, I apologize. I really do however struggle to put together this problem as described. I am glad someone has a good idea of what is being expressed here. Hopefully you can get it solved/realized/dealt with.

Thank you and well done.

Yes, this problem is extremely vague. But we've given some good starting points for this guy and he should be good to go.
