i know its probably been done to death before, but after doing a search, am i right in saying that the two 1st upgrades to reduce understeer are to install rear arb and bumpsteer kit?

bumpsteer

After a few years away from gtir`s i have bought another one. All the mods i wanted to do last time i can now afford , bumsteer was talked about when i last had a pulsar but nothing was available then, now there seems variouse options but i am intrigued to now why they will only last 2k miles, and what is an anti dive kit?
I was speaking to an Aus chap who had drilled out the tapered socket on the hub and simply re fitted the rod end/knuckle up side down, has any body seen this done? he thought this was the best mod(he does race his gtir though).

The ball joints on the bumpsteer kits have a habit of wearing out quickly in some cases.

The anti dive kit is a new front wishbone rear mounting bush. (plus spacer plates and bolts)

I know nothing about the age or problems with your car, how and where you drive or when in a corner you are getting understeer but I'm going to give you advice anyway on the two best things you need to do!! :doh: :doh: :doh:

We need more information to make any meaningful comments.

Of the recent people I've helped people with, the handling issues were caused by:

tyre pressures
tyres and tyres pressures
dampers
tyre pressures
tyres

I'm sure handling upgrades are like fat pills, people want to be told what they need to do rather than just sorting out the basics.

Alternativley take your front ARB off and pump your rear tyres to 40psi, that'll do it. ;-) :roll:

Excuse my tone but what utter rubbish, the "official" bumpsteer kit made by Powerstation/Whiteline has received criticism from some owners saying the Rose Joint type bearing rod end bearing had worn out very quickly and needed replacing but other owners say there kit is still going strong after years of use. Power station get the machining done for there bumpsteer kits by an engineering shop local to them, I believe this machine shop has over the years used the same parts but made by different manufacturers in the bumpsteer kits supplied to power station. This would be one explanation to some kits wearing out before others.

Personally, a couple of years ago I bought Gordon Kay's version of the same kit. The kit all looked exactly the same as the so called official one, it fitted perfectly and worked a treat. The bearings lasted about 8000 miles of hard everyday driving. By this time Gordon had stopped making the kit, so I was stuffed as I

I discovered that the bearings in Gordons kit were supplied by a certain bearing specialist, on contacting them I discovered gordon had used what could only be described as a "budget" bearing which funnily enough was very similarly priced to the one used in the Powerstion kit.

Through this supplier I found some very good quality professional motorsport bearings that would replace the existing bearings Gordon/Powerstaion used. I organised a group buy of 10 sets and have not heard a word of complaint, that was well over a year ago.

So, yes the powerstaion kits (were the bad rep comes from) do wear out quick but not all Track rod end bearings wear out that quickly.

Would losing the front anti roll bar make alot of difference? (with Teins, anti dive kit and whiteline lower brace already fitted)
I feel another 5kg coming off my car soon;-)

sorry, that was me being ironic :oops::oops:

For drag racing, it won't do anything for you and you may as well save the 5Kg

But I'd also drop your tyre pressires to 25psi and reduce weight transfer by increasing damper and spring rates.

Cheers,
Jim

Does anybody make these kits any more?

I tried dropping tyre pressures last time out at York. And it didn't make a jot of difference. First and last runs (30psi and 20psi) were identical to almost 1/100th

I always set my dampers to full soft as I think I get more wheel spin on launch if they're on hard.

To be honest I don't think my arb has alot left to do with the stiffness of the teins and the lower strut brace holding the wishbones in place.
