    Default cheap suspension upgrades

    After some advice on some cheap susension/handling improvements for my VP
    So far i've purchased , but haven't fitted
    Silverline front 30mm lowered springs
    Boge front lowered shocks
    Heavy dity sway bar links, and a set of nothalane bushes
    Front lower control arm bushes

    Now i don't really know all the components to a cars suspension, so can someone tell me some other things i can upgrade on the cheap, that would be great.
    I've heard V8 front sway bars are a few mm thicker( so i'm trying to rack one down), does anyone know about the rear sway bars?

    The V8 rear 'bar is 20mm vs V6's 19mm in VN-VP. I think you will find that the front 'bars are the same V6 and V8.

    It is best to consider and plan what you are trying to achieve before throwing random parts at the car - the result with the latter approach is likely to result in a degradation rather than an improvement. If you fit only what you have now, you will get a car that will understeer.

    Using a kit of parts from a single manufacturer is likely to produce the best results if you want to go further i.e. if you want to use the Silverline front springs find the recommended matching springs and dampers for the rear. The 'bars can be used to adjust the balance of the car i.e. which end slides first, with those in place.

    Tyres make a bigger difference than suspension mods. Matching them for brand and type front to rear is a good place to start. Any mods should then be tuned around them.

    Optimised handling and road holding on a wet road surface is different from on a dry surface i.e. don't go too far (stiff).

    It's probably worth spending an afternoon or two at your local tech. college or university library - they will have several good books on suspension theory - from basic, explicit, mods up to mathematical modelling.

    On a street car, driven every day, I prefer to keep it fairly mild; I have FE2 in a V6 with the V8 rear 'bar and standard bushes in good condition - cost SFA, is pleasant to drive and actually works on a wet road.

    to much misconception lowering dose not do any thing (it makes cars slower)

    exaple evo8 fe2 go any lower and you lose lap times

    fe2 is factory lowerd

    if you go lower you lower your rollcenter if you lower your rollcenter too much your car will screech tyers and slide a lot more

    if you have standard car than fe2 is a good upgrade

    Yeah i don't want to go lower, thats why i only bought 30mm lower springs, which would probably sit at the same hieght as my current sagging springs.
    I'm not sure on the state of my current shocks in the front, but the passenger side one makes some pretty bad noises when i go over bumps, so i'm assuming they could do with a replacement.

    Also, what are people's opinions on Silverline springs. I bought the front set new for $59, which i thought was a good deal, and i'm going to try and get a good deal on a set for the rear, along with another set of boge shocks at the same time..I heard boge were the same as KYB, and i've heard good things about KYB, so i'm sure the shcoks going in will be fine.

    I know i should be matching right parts and all that, but the springs and shocks i've purchased would have to better than the worn out compnents that are currently in there wouldn't they? Especially once both the front and rear components are installed?

    damn, all those guys at bathurst must have it wrong then as the v8 supercars are sitting on the ground. i wonder how they made such a big mistake when your never-ending knowledge was available right here all along.

    i always thought that lowering the centre of gravity improved handling, but i'm not after a track day weapon, just something that handles reasonably, and dosent compromise much of my drivability.

    [qoute] Tyres make a bigger difference than suspension mods.[quote]I have 215 Nankangs at the moment, which i think are pretty resonable.

    But i think it's just a case that a lot of my suspension components are worn out. My panhard rubbers were so worn that you shake the bar what felt like an inch either direction. Even replacing those made what felt like a huge difference.

    yea lowering dose help handling but spots cars have been worked out to handle the best they can

    evos have been set at max lowest rollcenter there rollcenter is on the ground whiteline has a lot of tec pages on there website that can explain

    a mini spool locks you diff so no race cars use lsd's so do some cars

    of course the race ones are a lot differnt

    a mini spool is said to strengthan your diff but i cant back that up im sure there are a lot of ppl that will try to but i have never used one

    i am about to put one in my mate's f100 so i will see how they go

    it's not just ride height that effects the way a car handles (and therefore roll center). it's also about having shocks that match the springs (shock and spring rates) and suspension travel is also very important. to cut a long story short, it's all about the complete package. just look at WRC car in a tarmac rally, they run **** all ride height, probably about 1/2 that ofa V8 supercar and i guess they are slow also
