140 Rally Suspension Setup Advice Needed

Hey guys,

I'm building up my '71 142E for RallyX use, and I'd like some suggestions on what springs/shocks to use. Right now I have Bilstein HD shocks front and rear and some crappy lowering springs. The car is over sprung and too low right now.

As far as I understand, I can use 164 front springs and 245 rear springs with the 240 upper spring mount. Is the 240 upper spring mount/perch a direct bolt-in affair to the rear of my '71? I think this spring combo will raise the car slightly over the stock ride height, and be stiffer. Does anyone know what spring rates the stock front 164 and rear 245 wagon springs are? I'd love to see exactly how much stiffer the 164/245 combo is over the stock spring rates.

I would love to get my hands on the R-Sport rally springs/shocks, but I'm not sure if they are even available anymore, or what part number to use to go looking for them.

I'm new to 140's and Volvo's in general, so any help/advice is greatly appreciated! Thanks in advance!
 
Early pre 72 164 front springs will be OK but late 164 springs are very thick and it will ride like an unloaded one ton dump truck, and be sky high up in the air.

Yes 240 upper rear spring perches will convert your 140 to 240 springs.

Early 164 front springs, and 244 rear springs would pick it up a little bit, and not be terribly jarry riding.

The other thing would be to read the green books, figure out the springs you need for the front and buy some blue coil springs.

I'll give you a big clue front spring free length is 308mm ~12" on a double flat top 5" ? spring.

Good luck with the racing.

Thanks for all the great info!

I've been looking around and found these numbers:

Stock 140 springs are around F305 / R90 lb/in.
The 164(early)/245 spring combo is around F360 / R145 lb/in.

I'm not sure how these rates will pair with stock valved Bilstein HD's, but might be worth trying out the combination. I don't really need to be higher than the stock ride height, but it wouldn't hurt I guess.

Stock Bilstein are intended to go with stock springs..
And springs and dampers for RALLY are one thing..
For grass-o-cross you want long and soft.
You wnat to be able to use brakes and the steering wheel to effect weight transfer AT THE SPEEDS you are typically doing.
Grass-o-cross does not have the high speeds and subsequent heavy loads from braking (say from 90mph down to 25 mph) or the big impacts...

Look at the Greenbooks where it says extended and compressed lengths which is under ST?TD?MPARE Fr?mre (front/forward if you are picky) and then 'sammantryckt' --pressed together and then utdragen===out-dragged --pulled apart.
And same for bakre..

Then check the travel in what you have..

Springs: no more than 10% stiffer

Rally--whole nuther kettle of squids..
 
Hi John,

Thanks for the input!

I'd like to go for more of a stage rally setup, as that is my ultimate goal. Without going to something completely custom, I was wondering what people out there who have rallied 140 series Volvo's have used. I would simply buy the R-Sport setup, but I don't think Volvo has them anymore.

I ran across a couple of people mentioning the 164/245 springs with KYB/Bilstein as a decent setup for rally. The higher than stock ride height seems not ideal to me, so I've been looking around and found the King Springs above, which are standard height and may be around 20% stiffer than stock from what I've gathered from people discussing their springs for different cars.

OK. Let's talk about the ultimate goal.
First, what's your name? Age? Imagined budget? Where are you located? Skills set?

And the important part: how many spare fenders, hoods, grilles, crossmembers, A arms in good condition do you have ready?
140s front suspension parts are not particularly strong--for rally use....
And everybody bashes stuff more or less constantly so you MUST have spares.

Second: when you say "a couple of people mentioning", that's nice but where was thta? who are they? Wot da fuq do they know about rally? What do they know about suspension? In other words, why should anybody listen to what they mention if they have not been active rally guys and doing anything to indicate that what they say is worthwhile?
If it was in English and posted somewhere in 'merikuh, what weight should "a couple of people mentioning" something be given...I know how much I would give it for weight...:roll:

Third: what are your plans to get the steering--a very important thing in real rally---down from the 14 or 15 turns of vague, sloppy steering to something reasonably acceptable like under 2.75 turns lock to lock? This one thing has been the end of many a rally 140.:oops:

You understand I hope that rally in USA (I am making the big assumption that you are in USA somewhere) has become something different than it was 20 years ago and even more changed from when I started 30 years ago..It is now much more a sprint type format and everything smoothed and simplified and "easier"--smoother, wider, faster roads suitable for the majority of the field---which means the 60% of the guys all in Subarus, and most with very very limited experience...One of the more active organisers, Anders Green from North Carolina is a very analytic guy and compiles data about entries..Between 2000 thru 2014 fully 43% of all people entering an event did three events before dropping out and disappearing completely.....that is a shocking figure and says to me that they have approached the sport with a erroneous idea of what they expect to do, what it costs and how much fun they need out of their efforts and expenditures..That means there is a constant churning of noobs in for a while and then dropping out far before they get a chance to learn much..That should be obvious..
Another statstic is that the average guy enters no more than 2.2 events per year..That means under 5 hours driving time..Again very difficult to accumulate much experience when in a year they get less time that I used to get in one afternoon practice session---and I used to practice minimum 2 times a week and average 5 events per month, sometimes--often more...(In a different sport in a different country)

So...inevitably I have to ask, IF you intend to actually enter rally events.....
then why a 140?
Instead of a 240.. simpler, stronger, better in just the areas that 140s are worrisome in...

I should say that realistically there is nobody in America or Canada who has consistently for more than 25 years pushed 240s are what I call "The MkII Escort of North America" and therefore "what should be the default rally car for every noob"...

And, bear in mind my business has mostly been Saab from 1984 thru 1999 and been a Euro Ford guy since 1973 (except a year when racing in France when i owned Peugeot 404 diesels--the other year I lived in a Ford van) so I advocate for the 240s from a different perspective than that of a "Volvo perv": I know how well they work in US and Canajian conditions....and know how poorly 140s did everywhere, even back home..

In other words, which is given more priority: doing rally as a legitimate entrant with a fighting chance in the 2wd field? Or insistance on doing a 140?

ALL these questions are important to think about before undertaking any effort towards modding the car..
 
Anyone ever heard of or use King Springs out of Australia?

Seems like they make "HD" springs at the standard ride height:

http://www.ebay.com/itm/STANDARD-SP...ash=item5d5e9b41c3:g:vh8AAOSw9mFWMcvT&vxp=mtr

However, I can't find any info about their spring rates or % stiffness over stock...

Of course they aren't going to post that information, or everybody will just buy 5" stock car springs locally.

Shameless plug:

I do have a spare 140 front crossmember for $250 plus the ride.

My reasoning for the 140 as compared to the 240 is the fact that I can get a 140 for $500 and a 240 for $2500+
 
It wasn't 500 but when I had my barn find 145 on here for sale there was lots of appreciation but no takers. Hope the original poster has enjoyed rally with his car.
I wouldn't rally a 140 just because the front suspension parts are twice the price of a 240 suspension even though technically it is a better setup. You will be replacing those expensive ball joints all the time with rally abuse.

Do you still have that car?

My ultimate goal is to have a daily driver that I can have fun on some gravel roads. I'm not gonna be doing actual serious competition as I'm a rather busy individual, but it would mainly be stop off on some gravel roads and go for a rip every once in a while. So, for the price, would it be worthwhile?

And they press in too. I'd rather use an Amazon with the bolt in ball joints.
