No this is not a "mine is bigger than yours" thread.
I'm trying to find out what size sway bars in the various 700/900 model Volvos.
The local Volvo specialist looked at his parts listing and reckons that the the 740/760/940/960s here in Oz all all the same i.e. 19mm in the front and 16mm in the rear (if it has one). There certainly are other sizes in the parts listing I have but it is US based.
I'll go first:
1990 Volvo 740 GLE - Stock - front 19mm rear is 16mm.
I've got 21/23mm on my car
EDIT: Just read that you want 700/900 series cars. Disregard.
Your specialist is wrong.
Turbos have 22mm front iirc and 18mm rear.
My 740t Wagon has a 24mm bar from a 88> 760 or 960 till 95. And a sedan rear sway bar so 18mm
760 has 24mm front and none in the rear due to irs and it being a hassle to fit the sway bar that did come on them to irs cars that don't have them.
I didn't think he was right but I didn't have the experience to fall back on.
My "Original Technical Publications" disk on the 740/760/780 models from 1982 to 1992 lists three bars for the front of the 740 namely 19, 21 & 23mm. For the rear it lists two ie. 16 & 19mm.
For the 760 it lists two sizes for the front 21 & 23mm and none for the rear.
My 740 has a 24mm Whiteline front swaybar and late-model 965 18mm rear swaybar. I want moar. I want like... 26mm front and 22mm rear.
Well, if you're willing to pay there are 25/25mm IPD ones.
New on sale from IPD @ $246US
and 2nd hand on Ebay.
Both options, however, suffer from the cost of freight to OZ (around $150US).
Edit: Just tried on the IPD site with my 740 listing and the sale price is not there - so maybe full price for OZ!
Hmmm 25/25 could be good. Wish it didn't cost $500 to find out though...
Too much sway bar is the wrong way to go , better springs are more effective. .
Talk to Ash about suspension tuning , he knows a wee bit about it. . ...
Problem is with stiffer springs I'd need more damper, which would mean revalved HDs or just straight up stiffer shocks. I.e. lots of money.
Nah , talk to Ash , or buy his 240 racecar!?
@jamesinc Dual 24mm Front Sway bar ? I got a 24mm Front Sway at VQ's place, and plan to run it first and will throw another one on if i found another one. Dual 24mm Front (Around 28mm ?) and 25mm Rear ? Maximum Stiffness ?
Well according to this 25+25 =29.73 and 23+25=28.615, so 24+24 may well be around 28.
Yeah, thats what i thought lol
I wouldn't do dual. I'd be looking at Springs and shocks before sways if you're that keen. The leverage on dual for track use just doesn't seem appealing. Diy coilovers would be the go
I might go DIY coilovers in the front with Koni Adjustable All round, but they ain't cheap
Thinking I might run two 19s on the front of the 264 seeing as the V6 sways are different and alternative sizes are rarer than rocking horse poo.... Need better shocks too as the 'modified' springs are ok, but the dampeners are just NUTTT...
2 series can use el Falcon sway bars. They have the dip already too.
Ok. Cool. Thanks @Vee_Que
You still don't have those Bilsteins fitted Calvin?! *face palm*
Assuming the sway bars you're comparing are the same design, stiffness is determined by d^4 (or d x d x d x d, if you'd prefer).
I am sceptical of TB-old-mate's assertion that twinned bars work out as mathematically neatly as he suggests, though. Every twin swaybar setup I've seen has been a bit shit. They usually have issues with binding and/or putting loads in the wrong place./in the wrong direction.
