What can be done to stiffen up a convertible?

[Joey Link]

I've been thinking hard about different ways one might be able to stiffen up a convertible. I'm curious to hear if you guys have any ideas.

Weld the doors shut. :)

[Joey Link]

You shut up :P

Get a carbon fibre hard top made

Wat have you done for the car already?? Cabrios are known for body flex.. I would suggest replace all your rubber with teflon or powerflex, then get good springs and shocks and RSM's from the E46.. But then again it depends on wat your trying to do

[smonkbmw]

install all stress bars. add in that bar that goes across the floor bars (ive heard it stiffens the car up well). besides that, custom cage.

[Van Westervelt]

And weld the doors shut.

Did the e30's ever come with those x-braces like the e36's? I think they mounted under the front subframe?

[PiercedE30]

nope, but you can make one fit.

Jeff do you have anymore info on the bars you're referring to?

[Mastrcruse]

I felt a difference in the stiffness (and less cowl shake) by installing the front strut bar. I searched before and got the idea that the strut bar has immediate affects on the vert but not the coupe.

So..
1) Strut Bar
2) bigger sways
3) shocks and springs
4) RSM's (I think these are damn important when upgrading)
5)The big butt strut
6) Custom cage
7) weld doors shut
8) weld a top on
9) just scrap it
10) Rob
