OK, do I need heavy duty rear springs?

TG, at 40,000 Kms, your Forester is barely run in. Won't be fully run in until around 70,000+ Kms ...

I have bought the new springs/shocks etc kit.

Lucas will fit them this Friday.
 
Spoke to Wholesale Suspension in Sydney (King Springs wholesalers) but they weren't helpful in terms of advice


I am REALLY surprised by this - they have looked after my suspension, and others here, for years. Did you speak with Penrith or Blacktown?

Call Penrith and ask for Matt - say I suggested you speak with him. Or PM me with your phone number and I'll have Matt call you.

I'm confused by that statement :confused:

I've dealt with the guys at Penrith a few times & found them fantastic :)

It was Penrith I spoke to. I'll try again given your advice, and ask specifically for Matt. Heasman Suspension called them too, and were told that they don't have any suspension kit for Foresters that provide lift as well as heavier duty. So I'm a bit taken aback at that. Will try again as you suggest.

Thanks

OKay, spoke to Pat, who was indeed very helpful. But unfortunately the news is not great - while King Springs do make a heavier duty shock for my model (2011 Forester X) they don't have a raised version on their part list. This could be just lack of demand with the more recent model, or it could be that there is some issue with the later model cars that makes it undesirable / impossible to fit longer shocks/springs. :-(

He will check with King re options, it may be possible to make custom length even if they don't have an off the shelf option, but that sounds very expensive...

So I'll wait & see what he comes back with. Meanwhile, does anyone know of any good alternative to the King/KYB upgrade combination?

Ratbag - so as not to hijack your own fine thread too badly - presume your Pedders kit is same length as OEM - ie no raise, otherwise you'd have gone for all four replacements?

No worries, mate :cool:. It's all about rear suspension problems - everyone's, not just mine.

I don't know what length the OEM struts and springs are supposed to be.
The Pedders are 715 mm from the bottom to the top of the top centre bolt (out of the car ... ).

They were sold to me as being a replacement for the MY06 SLS OEM assembly. Pedders said that they are a variable rate spring (more progressive than fixed rate, which Lucas warned me away from ... ), and that they are 17% heavier duty than the OEM spring. This should be very good for my purposes, without disturbing the balance and handling of the car when not towing.

Both Lucas and Pedders know what my problem is, and that my Fox will be used for towing a trailer. Both have seen the car. It is 40 mm lower than spec at the rear, without the trailer, or even a spare. Their recommendations are based on that knowledge.

I look forward to a good result on Friday morning ... :).
 
Sounds like the way to go Ratbag. I'll post a separate thread with my specific issue, as it is similar, but less solutions obvious for my 2011 model. Look forward to hearing your feedback after installation.
 
I just measured my wheel arch height to centre of hub.

Spec is F = 437 mm; R = 440 mm.

Mine is F = 434 mm; R = 400 mm - and that's just sitting at the curb, without even a spare wheel in the boot!

So I suspect that my rear suspension is, like a good tree, well and truly rooted ...

Yep, that is like a good tree for sure! :lol:

Seems that the Pedders variable rate spring kit is the way for me to go. Bolt off/bolt on. Off the shelf part. No assembly/disassembly of struts, springs, etc. Come complete with new bumps and all that stuff, including strut tops.

Lucas will fit them this Friday.

Are they SLS struts? It seems that for your use, SLS may be the way to go...

Would you be able to ask them to keep the rear strut tops? I'd like to have them if thats ok with you

Only too true!! :puke: :puke:

No. Not SLS. But variable rate springs, with heavier full load rating - about 17% heavier. This should suit my needs just fine, without upsetting the way the car drives without the tag-along.

Would you be able to ask them to keep the rear strut tops? I'd like to have them if thats ok with you

Lucas has a pair of s/h strut tops he will sell for $50-60. I don't know if these will fit your SF?

I will possibly/probably keep mine. They probably just need new shocks or springs, or both, and can be swapped in for non-towing use if the new ones prove too hard and bouncy for normal use. I should know what the go is within a short time of the new assemblies being fitted this Friday. Probably within a couple of minutes ... :poke: :iconwink:.

Watch this space ...

Meanwhile, some pics of the new ones:

Why do off-road spring manufacturers go for brightly painted springs? My Kings are bright yellow and rather embarrasses me with the "look at me, look at me" effect. Besides, those red Pedders look better than my yellow Kings. I'm more a red man myself. lol
 
Guzzla, I think it is the "bling effect" that is so prevalent these days.

IMHO, function should always take precedence over form, but we are going through a period of history where form has triumphed over function - BIG time! :(.

If it annoys you so much, take the wheels off and hit them with a can of mud coloured paint ... :lol: :rotfl: :poke:. That's what I will do if it gets to me. There is still a little charcoal grey hammertone paint left in one of the cans I touch up the trailer with ... :ebiggrin: :cool:.

I have never been a "bling" type of person.
Substance is important to me; looks aren't.

NL, if the new rears work OK when not towing the trailer, they are yours. I'll swap them for the help I need to attach my cargo barrier in place ... ;) :iconwink: :poke: :poke: - :lol:.

I had my extra arms and hands amputated at birth (along with the extra head ... :lol:), so only have two of each. Sometimes it helps to have four of each ... AND an extra head ... :rotfl:.
 
Gidday Folks

The new struts and springs went in the rear of Roo2 this morning. Some photos will follow when I get around to it.

The Pedders units have one more turn in the spring (7 vs 6 in the OEM SLS unit), and no SLS unit (of course). The spring coils in the Pedders also seem to be very slightly thicker, but I will have to run the micrometer over them. Anyway, it's not the thickness that's relevant, but the steel and other attributes of the spring that give a given spring a particular compression/rebound rate.

With the same crap in the back (BUT - plus a steel spare wheel/tyre = nearly 20 Kgs), the car is sitting 25-30 mm higher in the rear than before.

Driving is more telling. It is not particularly firmer so much as more progressive or smoother. A bit hard to describe. The ride is less harsh than before, while feeling more directionally stable and in contact with the ground better.

Going over known speed humps at 40 Km/h, the car doesn't bounce anywhere near as much as with the old rear end. Not as "sharp" on either the approach or the departure over the hump. In fact, particularly noticeably smoother on the departure side of the hump.

Jason at Lucas Automotive did the whole job in short order. Lucas and I talked about all sorts of technical stuff for about 2 hours. I learned a lot. He also reckons that he hadn't thought of one of my suggestions ... We can all learn from each other .... :iconwink:.

One thing I can tell you all is: do NOT do handbrake turns in your Subies. I have seen the resulting damage to the centre diff, and it wasn't pretty!

It will be interesting to see how it handles having the trailer on the back. Not ATM, however. Flaming cold and wet here :(. A good day for indoors, or going out for lunch with a mate a bit later ... :) :biggrin:.
 
Sounds like the difference between working /non working rear suspension! When i put the raised springs and new kyb shocks in blinky I pulled out 4 broken struts, It was like a new car after that. Just wish I'd had the time to do it before spending 2 weeks in harriteville driving up hotham everyday was an odd experience with ruined shocks and black ice.

Good to see it's all worked out, Don't happen to want a few bucks for the old shocks? I'm possibly looking at a koni conversion in the rear of mine.

NL got in first, mate. Sorry. I am sure that you can have any bits he doesn't want though.

While not gaining 40 mm at the rear, only about 25 mm, I think that it will not sag like anything with the trailer on either.

Funny how these things creep up on one. I have noticed that the speed humps have been getting harder and bouncier over the last year, but hadn't really thought about the rear springs until I took the photo with the trailer on the other day. Then it was very obvious what the problem was.
 
Good to hear the new suspension is to your liking :biggrin:

Sounds like you had a fair bit of weight still, so 25mm is good. The test will be with all the gear out of the back, if its sitting level then.

RB, idw can have the struts, I only want the strut tops (strut top hat with the 3 little bolts) which he cant use anyway, he has to swap his own SF strut tops onto the SG struts. Not sure if he realises they're SLS though...
 
Gidday NL

Thanks. It certainly feels much better to drive, thusly far.

Taking the (21 Kg) steel spare out of the boot and bouncing the car up and down on the tow ball made no difference whatsoever to the wheel arch/wheel centre measurement. It stayed at around the 425-428 mm mark - exactly the same as it was before I took the spare out.

It is also the same as it was when the two old struts were on the back seat.

I will hitch the trailer up at some stage during the weekend and see what happens then.
 
Interesting to see the difference!
