Ive just got the H-Sport swaybars, but what sould I do with the OEM's.
Are they better than the MC ones, or are the the same as mine?
Should I sell them?

 

Sell them to a Non - S owner

 

so they are thiker than the non-s ones?

 

MCS = 17 mm
MC = 16 mm
For MC owners to buy this, they must get it for $30 or less and spend on urethane bushings to give less flex and more anti-sway properties as 16 to 17 mm won't do as much as going to 19mm which is readily accepted by NAMers to equalize the understeer.

 

...or keep it, incase for some reason you need to put the stock bar back on. Such as but not limited to some kind of accident that renders your bar bent, wanting to do one of the stock auto-x thngs... i guess.

I kept all my OEM parts, so if the need arises, my car can be nearly stock in a mater of days.

 

Just toss it in a corner in the garage. If the need arises, you can be a good Samaritan and give it to a Cooper owner or keep it if you have some reason to go back to stock.

 

Sell it because with your "new found balance" you'll never want to go back to stock sway bar again. I love how mine changed the handling dynamics of my car.
