Click on the link to a whole thread on alignment settingson Charlie Brown's lowered NC.

However, CB seems to be adjusting for the track and there's little mention of tread wear and long term use.

I understand that adjusting to a more aggressive camber setting will affect wear but the mechanic's warning that the tires will only last another 5000ks (on a 3 month old car) is a little worrisome.

Tyre life was cut by about 33% (Still more than half tread on outside, nearly bald on inside) on my previous NB8A at 1.5 degrees. Wouldn't recommend it if you're concerned about tyre life. Might have improved cornering during daily driving, but that's only using the bumometer.

The mechanic said that setting the camber at -1.5 would be great for racing, but since it is so far off spec, tire wear would be excessive and the tires won't last me more than 5000 - 10000 ks.

Do any of you have similar camber settings and have found problems with your tire life?

Hi plib,

Not sure who your mechanic is but though this bit of actual evidence may help you, noting that you didn’t say if you had the NC aligned to the numbers you posted.

I have now done over 18,500 kilometres made up of normal driving and 5 track days. I have run upto -2.5 degrees camber on the rear and -2 degrees on the front. Current setup is -2.0F, -2.1R. I still have plenty of legal tread depth though there is slightly more wear on the inside than the outside. I estimate if I don’t do any more track days I will get about 25,000 kilometres out of these tyres. If I hadn’t done track but just ran the alignment I suspect that they would have easily seen in 40,000+ klms.

The correct setting for your NC with the Eibachs should be:
Front Camber -1.01 degrees
Front Castor 6.36 degrees
Total toe in 2mm

Rear Camber – 1.56 degrees
Total toe in 3mm

Hope this info helps

Apologies for hijacking.. I'm in Sydney and about to get an NC RC..

Can anyone recommend where to source Eibach springs from, where to have them fitted and where to have decent wheel alignment sorted.

thanks

Hrm
I heard somewhere that having more negative rear camber results in less rear end grip? That doesn't sound right does it?

I'm running -1.75 camber /2mm toe at the front, and rears were left at Lou (Straight Talk Suspension)'s default settings (which I think is -1.25/2mmish). Front camber was originally at -1.5 but I found that with my retarded babboon driving style I was still wearing the outsides of my tyres quicker than the insides

jonno.

Salamander,
don't be afraid to start a new topic, using a descriptive title e.g. "Where to Source Eibachs in Sydney". Then you'll have no need to apologize for attempted hijack, and you'll be more likely to have someone who has appropriate information read your message than if it's hidden away under a thread about wheel alignements and tyre wear.

Sorry, can't help with the Eibachs.

Cheers,
Alf
