348 anti roll bar upgrade

348 has a lot of chassis flex. Stiffer bars will likely lose most of their effectiveness by making the chassis flex more. The CH cars got away with it by having a roll cage that stiffened the chassis.

 

The 348 Challenge sway bars are same as on standard 348s but they have different sway bar bushes. The roll cage usually significantly stiffens the car body. The 348 Challenge has a roll cage, not just a roll bar:

348 challenge bushes will most likely be delrin. That should stiffen them up. Or Energy Suspension poly.

 

The 355 Challenge 1999 has two options:
Standard:..............159353 front, 159303 rear
"Upon demand":.....176031 front, 176032 rear

I guess the "Upon demands" are thicker.

 

Delrin bushings anre incredibly easily to machine or have machined.

 

Wanna make some for my challenge roll bars? 24mm and 19mm.

 

Is this just a project for fun or is there a performance reason to do it?

 

Stiff sway bar and/or bushings

I remember way back one of the Ford SVO engineers a dear friend Doug, big red head bearded biker dude, was one of the best.
They had Jackie Stewart tune the suspensions as they could just not get it to stay on the road in dry much less wet conditions. Sir Jackie was hired, came in and softened everything up making it a beast in dry and wet.
The entire car needs to be taken into consideration with real seat time to get it right. Something Google and here say just cant do.
I have 2 355 challenges with 2 different style roll cages and weight distribution. The set ups on paper are not remotely similar. Both 1995 355 challenges.

Street is not track

We have a guy here that currently races a 348 Challenge thats on top of things. may want get his opinion

Get it out, lots track seat time then make small adjustments. unless you just like to google race but I understand that's quite popular today LOL

 

I don't mean top be a curmudgeon. You can do a ton to these to make them suit your feel and liking.
Shocks are my favorite. With all the new designs today you can go bat poop crazy. Our cars the shocks are like 300 years old in design.
I need to do an upgrade one of these days but I'm check so 15k on shocks I rather give it to my hooker

 

I see in the online catalogue that the 348 standard sway bar bushes are red and the Challenge bushes are white. Did you buy the red Ferrari bushes or red aftermarket?

Also, the 348 Challenge uses different (harder I believe) wishbone bushes, front and rear. These should "sharpen" the handling further.

 

Have a look at Maranello (ferrariparts.co.uk) website. They appear to have Challenge anti roll bar and wishbone bushes in stock.

 

Driving on the street and tossing it around corners I never find myself saying, I wish it rolled less and was stiffer. One thing the factory shocks oil and nitrogen are 100% shot, start by having them rebuilt perhaps. I did, made a world of difference.

 

I think you can still buy the cage or have one built. Good luck!
