Tuning ARB and the springs from a sporting why?

[darkwave109]

alot of people are telling me to get ARB and the springs from a sporting to fit my seicento s so i can lower it...but the thing is i have the complete history of my car and it says the whole suspension including springs basicly the whole lot has been replaced 6 weeks before it was sent to the scrappy........so why cant i just buy the lowering spring and fit them in..i can get ones for my car for £48 from some one i kno whos dad owns a garage.

You can indeed just fit the Sporting Springs to your car with the existing dampers.

If you go lower than that, you can still use your new dampers, but they won't last as long.

ARB is optional.

ARB will stop the car rolling about as much so a worthwhile buy, your car wont have one

However, cause and effect, on rough roads the ARB can cause the car to dart about a bit at the front.

Anti roll bar (ARB) uses the extension of one wheel (inner wheel in a turn) to push down the opposite wheel, so it transfers grip from the side with the least grip to the side with more grip. The car doesn't roll about so much but the ultimate grip might well be reduced. ARBs also make the suspension stiffer.

However, beyond a certain point large amounts of body roll will lift a wheel anyway, so the ARB should either cause car to sllde before that happens or reduce the roll so the wheel doesn't lift.

Then again, if the ARB is too stiff the compressed loaded side will also compress the unloaded side again lfting the wheel. Its all about compromise.

I think that's about it, sadly I lost my David Vizard tuning book years ago.

Pretty much. Try driving a Sporting and your car (if it's an MPI/1100 car it will have the ARB anyway, though!) back to back.

My W reg 900 Sei** has a front ARB but nothing on the back. With Cinq wheels and P700 tyres it does roll a bit but it sticks nicely so I'm not to bothered.

** 900's need all the help they can get & decent tyres let you keep the speed through bends.
