98 740il e38 sway bar help

So im working on making my e38 a fun weekend car but i have a few issues. there is a lot of body sway and yes i know its a massive car but my sway bar just broke( rusted through) and im thinking if i get a better one could i reduce some of that without spending money on coilovers or springs?

im lookin to do the 6 speed swap later on after i fix up the suspension a bit. and the engine will last a lot longer its only got 50k miles on it and the chassis has 130k but i keep it in the garage and do a lot of rust work/ rust protection.

but main issue is sway bar should i look into after market parts or is there not much of a difference for the OEM part and anyone know how to put that in?

Sway bar

I did a little research and found nothing after market for our cars. Since you have an il you are ahead of the game because you have a rear sway bar to begin with. The short model doesnt, not even the sport model much to my dismay and suprise. You might be able to upgrade if you go to the Sport model front sway bar, I think its bigger. Replace the rear and be happy to have one at all. A new one with new bushings and links should twist less than an old rusty one anyway.

Most car manufactures put a bigger sway bar on heavier models. Since the 750 has a V-12 you might do some resreach to see if that sway bar is thicker.

Look up the part number for the 740 sawy bar and see if its the same number as the 750. If it is'nt chances are its bigger.

if your car didnt come with a rear sway bar, you most likely dont have the endlink brackets on teh control arms. easy fixt though. drill and tap a hole for bolts for a bracket or weld brackets on.
this is somethign il do this year sometime too.

yea its got the rear sway bar but the front one rusted through and snapped but i ordered a new swaybar, bushings, and control links. that will be taken care of, now anyone know about lowering spring? im lookin to get some H&Rs to drop about 1.5 both ways (still researching parts and ride heights) but can i just put them on without wrecking anything?

theres alot of threads on it. search "lowerd e38" or "slammed e38" seems like eibach has the lowest. springs are around $215-300 for a full set. buy new struts and shocks while your at it. thats what im going to do when i have more $.

its been a while since i last posted here because ive had a different car to drive. The previous sway bar and links i ordered were out of stock and i somehwat put that problem to the side. Im looking to buy one off ebay for cheap and was wondering if anyone knew the size of the sway bar or a part number for it. I can pick up a used pair for cheap on ebay but dont want to buy it unless it will for sure fit. if anyone know the part number or how to find it that would be great because i just cant find a clear solution. also i am wondering if it could put a sway bar from a 2000 740il sway bar and door on my 1998 740il.

Look at realoem.com to see if part numbers match up.

I found a good replacement but i cannot find any instructions for a sway bar install on a e38. i did find an e46 and e36 video and for those its as simple as connect to the end links and then bolt the bushings to their mounting points but does anyone know if that is the case for a 7er?

Id love to go look under my car now but I am currently at college and am planning to put the part in when i get home.
