how much of an effect does the rear camber have on handling after being lowered

[e.pie]

since the rear camber can't be brought into spec after being lowered, how much does this effect the handling of the car?

would it actually be better if I raised it back to stock levels, it's on bilsteins so it's not a big deal to raise it back up

The major issue with alot of - camber is inner tire wear.Drive for 3-4 k miles on the street and you will be surprised at how good the outer tire looks but you are corded on the inner.

I have the TEIN-RA suspension on my car and it is lowered by about 1.5" all around. Due to this, my rear camber is about -2 degrees and we were unable to set it any less than that. Am also running 5mm of toe-in on the rear.

I am running 17/18 OZ Ultraleggera wheels with 265/35/18 tires in the rear.

The car is very neutral in corners and grips magnificently, in my opinion. And actually, my rear tire wear is pretty even across the whole width of the car.

hey cool you're in the netherlands, thanks for the info

ik woon in belgië, maar mijn nederlands is niet zo goed

do you guys ever have any NSX meets, I'd love to attend one as soon as I get mine shipped over from the states

where can I get the kit, I've only seen one kit but it required sending the parts off somewhere to be modified

Yes, I live in Rotterdam
I believe the Belgium guys just had a tour in the Ardennes last Sunday.

Also, there will be a big event in Le Mans next month with NSX people from France, Holland, Germany, Swiss, the UK and also some from the US and Japan.

Do you already have your NSX or did you just move to Belgium in advance and have your NSX shipped later.

There are a few camber correction kits that can help you get back into spec or better if that is what you are searching for.

This first kit is $355 for the rear camber correction. You can either send in your upper control arms (rears), you can do it yourself, or you can have a compentent local mechanic install them.

Dali also makes a kit for $500 for the rear camber correction. You have to ship your lower chassis mount to dali for install.

FYI, Thom's camber correction hardware was covered in great detail here.

yes I moved here first, I don't know it will get here in time for next month

hopefully it will though

As far as your original question goes, the answer is that for street driving, you won't notice any real difference in handling due to increased rear camber from lowering 1-1.5 inches.

The major issue with alot of - camber is inner tire wear.Drive for 3-4 k miles on the street and you will be surprised at how good the outer tire looks but you are corded on the inner.

Inner tire wear is 95% due to toe, not camber. Its a common misconception.

The excessive inner tire wear noticed after lowering a car is because you are also increasing the toe angle which increases wear (which is why most people blame the camber).

For racing or high performance driving, up to around -3deg camber is a good starting point. Daily/street driving, you probably won't even notice.

But if tire life is a concern, fix the toe. If you get a camber correction kit, it'll still wear the inner tire if the toe is left alone.

no I'm not too worried about tire wear and daily driving, I was concerned more with how it would effect the handling on the track, on my old car adjusting the camber made a world of a difference in handling

with no camber in the front and a little over 2 degress in the rear I'm not sure how it will change things

Yes ,I neglected the toe,which is significant on the 91 specs.There is a thread about some folks running 0 toe and increasing tire longevity.I still cant believe though that even with 0 toe and say anything greater that -2.5 camber the inner tire will wear the same as the outer,if most miles are highway and not track.

You definately do not want to run 0deg camber in the front. Even factory grocery getters specs have some camber in the front. It improves cornering at speed.

If you're taking it to the track, I'd probably start at around -2.5 to -3deg in the front and -1.5 to -2.0 in the rear. As for toe, probably around 1/16" toe out in the front and 1/16" to 3/32" toe in on the rear.

See how it feels. Adjust from there. Toe will dramatically affect straight line stability, stability under braking as well as turn in. Camber will mostly affect overall cornering speed and adjust over/understeer conditions (generally).

Are you referring to the front or the rear? And perhaps confusing them with each other?

The phenomenon of inner tire wear generally occurs on the front tires, not on the rear. It can be a little better if you do more hard cornering, a little worse if you do mostly highway miles. And it can be greatly exacerbated if you have a suspension problem, like a ball joint that needs replacing. Trust me on this. :frown:

The phenomenon of tire longevity and tire wear generally occurs on the rear tires, not on the front. This is the reason that Acura reduced the recommended rear toe from 6 mm to 4 mm (and made it retroactive to all NSX model years). This is also the end of the car on which some folks reduce the rear toe to 2 mm or sometimes, as you note, even 0 mm, to increase tire treadlife (at the expense of a slight degradation in handling).

Ken I can attest to all points:wink:My thought process is based on the idea that - camber subjects the inner tire to more heat and stress going striaght regardless of front /rear.Of course toe with constant scrub soto speak will place more stress than simply camber I can't believe that someone driving on a "slammed" nsx even with 0 toe still would have even tire wear
