Does lowering/changing the suspension effect the handling from the original spec?

One of the things I loved about my 6 was the handling and damping. Most of the ones on the market now have been lowered or non standard suspension. I personally prefer my cars a bit more ninja

Yes, of course it does. Any difference in geometry, suspension, weight will have an effect on handling. And everything is a compromise, even the standard set up, it can be improved.


RE: Suspension - thoughts. - Dum-Dum - 09-10-2014

Definitely!

For a start the bottom ball joint is further out and further forwards than the top mount giving the standard camber and castor but shortening the distance between the 2 increases camber and castor.

It also can induce bump steer (where the steering arms aren't level with the rack and going over a bump causes the car to toe in/out die to the movement of the suspension effectively shortening/lengthening the arm).

Theres also al load more characteristics with COG, Roll centers, roll resistance from stiffer dampers, weight transfer that are all altered.

And the ARB wont be horizontal any more so in a perfect world youd have adjustable drop links.


RE: Suspension - thoughts. - Paisleycheesewarrior - 09-10-2014

Cheers, so I need to stick to an unmodified one.

If it has adjustable suspension could I get it up to OEM height, or will it still be inherently different?

Not sure i totally agree with you there buddy.

Ball joint sweep distance wont change so wont be further in or out unless lower arms are modified.
More camber perhaps but castor should be the same

Bump steer is easily rectified with balancing and centering the rack too, this is a more common issue of bump steer. And usually the sweep of the track rod arm can thus be matched to the lower arm sweep.

Tbh any 306 you buy now will have different handling to when it left the factory anyway!

Saggy beam and tired shocks make a huge difference for a start...

One with a decent 40mm kit and rebuilt beam will be better than one with 14 year old standard parts.


RE: Suspension - thoughts. - Rippthrough - 10-10-2014

Matching the tie rod to the wishbone sweep won't remove bump steer on a car with a Mcpherson strut, far from it.


RE: Suspension - thoughts. - Piggy - 10-10-2014

It will help dramatically though

2nd what piggy said.
