Suspension and Shock Absorbers

Post by **SteveP** » 28 Oct 2008 01:32 pm

Chris, you have an unfair advantage - I know how well them wheels/tyres combo stick

To be fair, that 343 is on original suspension iirc (it certainly bounces terribly!:lol:) , so I would've thought yours with Monroes would've been better anyway.

I was on mismatched tyres on steelies when we went to Haynes though mate. 300's are really forgiving with bad technique, do the same in an Avenger or something and you'd be in the hedge, but that doesn't mean you should always use the bad technique!

I didn't realise quite what a Stevie_P style moan that post came over as, must be something to do with those parts!

'Til the neck of your chosen vehicle can be rung I wouldn't worry too much about hypothetical bhp and torque figures.

Even that doesn't always work-seen people get giant killing results in 1300 BDH's next yr back with full blown 2 ltr BDA's and nowhere to be seen.
Confidence in your ability and your car's is worth a lot over a mile.

To be honest I wouldn't trust most of you to drive a knife through warm bread-but that's another story, boom .boom

Now admittedly I don't have much track time...but...you cheeky bugger Chris, I certainly know better than to do numptyish things like braking mid-corner

I was struggling in the low speed corners with not being able to turn the wheel fast enough (being a fan of PAS, I'm not used to this 4-turns lock-to-lock business), and the crazy body roll (courtesy of the front suspension being so screwed) causing 'interesting' behaviour. Funnily enough, the car seems to sort itself out at higher speeds.

Anyway, with smack-talk of that sort of calibre, I'll have to call for a showdown on a track. I demand a re-evaluation with a car that isn't broken

cheers

good luck... you guys have to have a showdown at an autosolo or something - sorry foggy but my pennies are currently on chris... he does seem to be able to peddle 300's pretty damn well!

Just a point, we all "know" not to do numptyish things like brake mid-corner, however it's not knowing... it's doing... I "know" how to do quite a few driving techniques, doesn't mean I remember to use them at an appropriate time - thats what practice is for

My pennies would also be on Chris, not least because he has much more competition experience than I do...but I feel I have been done a disservice, so it'll have to be a showdown at dawn now

cheers

Haha, I really wasn't meaning a dig at you Foggy, just a general "we should really learn to drive before we muck about". I can't drive as well as I want to, for this one perfect point Jason makes

I'd suspect 90% of people dont know why they want to do x/y/z to their cars, a bit of play time in a field/ organised carpark changes that a bit, as I'm sure you will have noticed.

what difference would it make get single or multi springs?

I think you can get the leaf / de dion setup to perform pretty well for road use up to say 200bhp...but beyond that or for competition use, I think it's going to struggle. My plan is to stick with the standard setup (with stiffer bits) for the 343, but consider multi-link for the 360, depending on how the standard stuff copes with 250+bhp.

I'm thinking I'll probably end up with multi-link on the 360, eventually. The phase 1 V70 AWD rear subframe is fairly compact (whereas the RWD IRS units aren't, particularly), and I'm sure there are loads of suitable units outside of the Volvo family.

The de dion unit is not a bad set up to be fair. Its basic but quite good. Give it the correct spring poundage and suitable dampers for the car and it will work well. The biggest problem for higher power 300's is spring wind up on take off.
For all the work of going to a multi link rear end i do not feel the results would be worth it. IRS would have to be the way to go to get any real improvment.

When I say multi-link...I mean either double wishbone or one wishbone and two link-rods. Multi-link covers a multitude of sins...and is even more of a blanket term than IRS! In this case I mean a setup like a 760/960 has.

cheers

Thats the way to go
