Yeah but it turns back into a frog at midnight

He needs to look outside of the box... the Lexus positions are not law, only suggestions, if the tyres are wearing move the angles to addresses the reason.

Hi K33rjd Maybe you need to see things from my side of the fence and hopefully this might correlate to your experiences with the Lexus IS200/300/sc. This club contacted wim five or so years ago in an attempt to explain the historic rapid inner front tyre wear. The reason as you may or may not know is the camber/ castor relationship on the corner. I found the scrub radius migration was incorrect allowing the outer wheel to lean to far negative. The only way to reduce this migration is to reduce the castor but on the IS200/300/sc this angle is fixed, which in it's self is interesting since there's three global positions for this... Asian, European and GB, although all the control arms are the same? I wrote a procedure that would "indirectly" adjust the castor position, reducing the migration maintaining a scrub radius within the steer axis, in truth it was an easy fix. Further research was needed to ensure the suspensions articulation during bump and weight transition was maintained and it was... from this i can only assume there was a major "error" between the IS design and production. In order to stop owners traveling hundreds of miles to us in desperation to dissolve their complaint i released the data and procedure to this clubs "knowledge base". Having removed the inner wear the only common patten of wear was under-inflation so i moved the OEM pressure from 33psi to 35psi. As i am sure you know "within reason" the Geometry calibration positions and tyre pressure's offered by the manufacture are "suggestions" not law, since there are to many variables. wim was asked to look outside of the box to solve this problem and we did, i'm not interested in belittling Lexus but it is what it is.

Thanks for the kind words everyone.... Initially i was distraught, i've worked so hard trying to get the centre finished and then some (edit) smash a hole through the building.... today i feel more at rest about things since in truth they've failed in life no me, so i can dust myself off and move on head held high. Everything is insured but i still have to replace the stock in the mean time which is bit of a bugger, but hay what can you do?

Why do you say tracking alone is not the answer? i'm interested as my four tyres have all gone on the outside shoulders (after 28K) I am about to but 4 tyres and get 4 wheel tracking done at Peak Performance in Llandow (near Cowbridge). I assumed this would be sufficient. Most grateful for any advice. Tracking's line of sight is linear, it can deal with toe issues but.... your car also has camber adjustment so the machine needs to read the vertical position of the wheel as well.

Welcome to LOC..... everyone's nice here, your in safe hands :)

The F1 asymmetric does not handle well on the 18" wheels.

Thanks for the feedback... I'm pleased you noticed the difference, now you know why i warn you to learn the car again, ever more so in the bad weather today.

Stunning show of support, i tip my hat to everyone involved "thank you".... Plus we can rest assured other people will be given a chance of life with this money aimed to irradicate cancer.

Have a nice one fella :)

Hello and welcome to LOC :)

Corner weighting should mean moving components like fuel cell or battery or even adding weight to obtain the correct balance. Some people think you just adjust the coil perches to move the weight.... that is not the correct way to do it. I feel only the serious track car would benefit from corner weighting.

As for "no, no's" not really.... just be wise..... Thing is with the dampers you can really play with transition limits as well as ride comfort. Transition limits changes the way the chassis articulates, submarines and squats. Most times owners want a steady state condition which is perfectly understandable but i feel this misses the real point of adjustable bump/ rebound. Play with it.... back them right off, then turn them full on.... feel the difference and decide what works for you...... As a heads up the actual positions make no difference to me during a chassis calibration since the car is static on the rig.

It's good to play with the damper settings..... I prefer the rear to be soft so she squats corner-out because this helps with the tyres saturation limits.... but that's just me.

The optimum would be to keep the wishbones and steering arms horizontal, this will maintain the roll centres and the roll couple. As for the dampening, there isn't any settings?.... Initially be guided by the manufacturer then adjust incrementally front or rear (not together) to find the ride that suits you.

They are superb..... Give +- 1.75d which is just what you guys in the low club need... Fitting was easy so happy days all round.

The problem we have is the MOT is 2/3 opinionated, so it's easy for the testers to set their own standards.

Yeah, like mini-wozz says keep em coming :)

Bazza when mat gets back i have a good idea where that bottles going

This condition is nothing to be worried about, as alarming as it feels or sounds it's nothing more than the reverse of the steer action/axis and the few feet you experience this will not harm you or the car. I could pants on all day about the reason why this happens but trust me it's a Tom Jones condition

Hello and welcome to LOC.... That is one nice looking LS, lucky you.

Congratulations.... I tip my wine glass to you all tonight.

When's JAE? Some time in September mate. Think you are going this year Oh no this reads like another LOC/wim xmas bash hijack.... "what a night!".... Jokes aside we should be there this year,

Abouy £100 mate. You should wait till the next LOC day at WIM and make a whole day & night of it :winky: And dose anyone know when this will be, Tony ??? Blimey, no not yet, i've got so much going on early next year i don't know how i'm going to manage..... I would think mid to late summer. Yes but it Would be before JAE right ??? When's JAE?

This is night when the boys brake the news.... "you know what love" next year i'm going to fit a "?" to the Lex. What's it going to be
