Remove rear sway bar?

I would like to have your pro's and con's on my idea to remove the rear sway bar on my Berlina 2000.

Current Situation:
I have shorter/harder springs (Eibach), new dampers (Bilstein front, Spax rear) and a new bigger sway bar in front, and also renewed all bushings. Compared to the old suspension (+40 years) it corners way better and faster. But: it somehow feels like a bit too much grip in the rear. It is not exactly understeering, but like a slot car taking a narrower circle... sorry for that weird description. For a track car that might be perfect, but I would prefer a little (!!!) oversteer.

Then I came across Alfaholics' recommendation to remove the rear sway bar on cars when using their handling kit - might that be the solution in my case?

Any experiences appreciated
Joerg

Worth a try, sounds like a similar setup to Alfaholics and Classic Alfa’s fast road offerings.

You stiffen the end of the car where you want less grip. If you want more oversteer generally you'd want a bigger rear bar, not smaller.

105 Alfa's are prone to oversteer, particularly when you try to put down power before the car has straightened out. That is why many people who drive fast remove the rear bar. I have tried several combinations and my favorite for fast road driving is the stock bar on the front and no bar on the rear with Shankle Super sport springs which are similar to the ones sold by Alfaholics. You generally need less bar with stiffer springs.

Wow, you're quick

OK, your explanations and the overview sound understandable, so maybe the original bar in the current setup is what I would like to feel in corners.

Thanks!

You can just unbolt one end and tie it up to try it out. If you like it better then you can remove the whole thing.

I'm on my third fast road Alfa (2 coupe's and currently a saloon), and have fitted the Classic Alfa Harvey Bailey handling kit to all of them.
(Lowered, stiffened springs front & rear, + 29mm front anti-roll bar.) Each time fitted with Koni Reds, half hard front & full soft rear
I've removed the rear bar in each case, and find it perfect.
On the current Ti Super Rep, I have adjustable top arms dialled in with one degree of negative camber and it really helps the turn-in.

I'm not saying it doesn't ride well, I just prefer to have a bit more lively rear axle. Probably I'll give a bit more negative camber in front and then it's perfect. Hard to describe anyway...

Thanks for your input
