Inner Edge Wearing??

A little background info.

2001 R34 GTX-T, Bilstein Shocks, Whiteline Springs, Rear Whiteline Camber Kit, Yokohama A539's.

I was changing oil tonight and found the front tyres (the right in particular) are wearing more on the inside edge. The right one appears to be almost worn flat on the inside edge??

I was advised by friends with similar suspension mods and by Fulcrum that a front camber kit wasn't necessary?? If this is the case, why are my fronts wearing down so quickly?

Note, have not been to any track days.

I had a 2x rear whiteline camber kits fitted by Fulcrum 2 days after I fitted the Bilstein/Whiteline Suspension with a mate.

They also carried out a full 4 wheel alignment and 4 wheel balance.

This was about 2 1/2 months ago.

Abo Bob> I can't find the settings, but Fulcrum have agreed to take a look and fix whatever the problem might be. They said that they may have wrongly adjusted something. Good service if you ask me.

GTR_Legend> I can't remember all of the differences. The ones I can remember are that it has a upgraded stereo system, and also it is a newer model revision, mine being a little rarer as it is a 2001 GTX-T. I believe it also has the Garrett BB turbo, but I am yet to confirm this. Here is a link with all the different skyline models. It is in Russian, but you can use Babel to get a rough translation.

did u get the tyre wear sorted out?

i lowered mine ,, and noticed that my front tyres are also worn on the inside,,

was told once by someone that i won't need rear camber kit,, but might need front camber kit,,

so thats different to your setup,,, now i'm confused,

so can anyone confirm what camber kits are needed for r34's when you lower it?

Front ro rear kits????

Front camber kits are generally not required unless you have bent something. You will notice that on the whiteline web page they only ever list the front camber kits for skylines as optional or for club/track use. The front suspension geometry doesn't get as badly effected by lowering as the rear. Suspension for the 33s and 34s is basically the same with only a minor shock mounting change to the rear.

I have always set my GTST and GTR like this:-

Front

camber -1.5deg to -2.0deg

toe in/out 0

caster as much as I can get....

currently 5.5deg on the GTR and about 8.0 on GTST

Rear

camber -1.0 deg

toe in/out slightly in, maybe 1mm to 1.5mm each side

These setting seem to work well, I have never had a problem with uneven tyre wear on the road or track.....

Hope that helps.

P.S. The rear does have some factory camber adjustment, you may find this is enough but it wasn't for me in either the GTR of GTST. The front does not have any camber adjustment but after lowering the GTST sedan its camber was right on -1.5deg each side which was perfect for me and the GTR I fitted a front camber kit as I go overkill on everything with it :wassup:

Fulcrum apparently said that everything was as they left it, so I'm not sure. As JL mentioned it could have been due to bending something, but that hasn't happened as far as I know.

My settings are pretty much what JL mentioned as he is the one who fitted all my suspension bits except for the rear camber kit, Fulcrum did that.

My thoughts are for the couple a hundred I can get the front camber kit and be done with it.

Piece of mind ...... maybe overkill but who cares.

My 20 cents worth......................

In order for the 1.5 degrees negative camber not to excessively wear tyres on the inside, you have to make use of it. If you do a lot of freeway driving or live in traffic then it is not using the negative camber. Similarly if you don't drive it hard through corners at every opportunity.

Personally I would never have 1.5 degrees negative camber on my driving to work car, it has 0.5 degree and I add 2 degrees for track work while it is jacked up to change the tyres.

Sorry Sydneykid. I may have misinformed with my last post. My rear camber was set by Fulcrum to -1.0deg. The front is stock setting...untouched.

As for driving of the car, I don't think of myself as a "Schumaker" for street driving, but I'm no "Driving Miss Daisy" either. :headspin:

I don't drive Miss Daisy either, but traffic and freeways beat me every time. The reality is, tyres wear on the inside (only) from excessive negative camber or excessive toe out. That's it, there isn't any other reason. :)

OK. So would upgrading to Whiteline Springs, Bilstein shocks, and Whiteline Rear camber kit cause Excessive negative camber or excessive toe out?

Maybe a little too much negative camber, shouldn't affect the toe at all. We are guessing, I would get the alignment checked, stick up the numbers and some of us "experts" will be ablet to help.

The car will be out of action for a couple of weeks, but as soon as I get the figures I will post them.

Thanks for the feedback. :thankyou:

Run your hand across the worn part of the tyre, if feels a bit furry when you run it across at a certain angle it is due to "feathering" which on the inside of the tyre would be due to excessive toe out. Lowering the suspension of the car will give the car more negative camber. Think about it. As the suspension lowers and the tyre moves farther up the guard, the lower control arm pushes in at the base of the wheel and produces more negative camber. The solution: raise your suspension again or buy a camber kit (in order for it to be adjustable)

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !

      By GTSBoy · Posted

      It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
