R32 wont fit.

you just get some run of the mill shockers and springs (harder ones)

Or you can fork out $$ and get coil overs and stuff then you can play around with heights and stuff also.

Ive got 250lb rear springs and some hard bilstein shocks in my rear.

Previously i had some softer shocks and the squat was too intense. Harder ones have sorted my problem but not as much as i would like. I still have a bit of issue.

I do have 500lb's siotting next to em i will install one day. And maybe play around with shockers also now ive found a decent suspension place here that doesnt rip me for mega $$

Waiting for SK too see this one :P

Well you didn't have to wait too long........

Stiffer springs are a band aid, why don't you fix the problem properly?

I don't understand the logic. It's got too much camber change, it's not too soft. Stick 500 lb springs in it, fantastic no more camber change but now it's too hard. Fix one problem and create another, what a good idea :confused:

depends what you clas as hard for youself though, wouldnt that then come down to personal preference?

If im not loosing any traction, but gaining. Then i'd say thats a win for me considering i havent spent a sent as its all spare srpings/shocks that i have sitting here that came with the car.

Yeah its not having something made up to adjust it. That for me will happen if my cheap fiddling doesnt work.

But the stock suspension is far too soft in the HR31, it does need stuff a fair portion harder

i've just put coilovers in the front of my hr30 now they have 400lb springs, the car is not driven at the moment and i'm glad as i'd say it would be not nice ... all i have to do is push down on the front and it just bounces like a bobble head dog..

when were the shocks last changed?

well got any other ideas SK?

from what i can see, theres not alot you can do with the trailing arm IRS in the hr31's to stop the huge camber changes apart from limit the travel with harder suspension... :(

Sorry, but I simply don't have the time to write a long explanation on the workings of a trailing arm rear suspension. Simplistically, the idea is to change the wheel's movement arc by repositioning the mounting points. Offset bushes are a good place to start, effective and cheap. The next step is redrilling the mounting holes. By moving the inner mounting points upwards in the chassis you can lessen the dynamic camber change. By changing the realtionship between the front and rear mounting points you can affect the squat, hence lessensing the need for excessively high spring rates. By moving the top mounting point you can lessen the static camber, this is helpfull as it can be diffcult to achieve the balance by only using the lower inner mounting points.

The Nissan trailing arm rear suspension has been popular since 1969, so plenty of people know what is necessary to be done. There are a number of books on the subject, the one written by Peter Brock (no, not that Peter Brock) on 1600's is a good place to start.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
