camber adjustment in rear

[nsxinohio]

Okay, I had to take my transmission out to put a new clutch in. When I was removing everything I made sure to mark the position of that little washer with the hash marks on it in the back bolt of the lower control arm b/c it has to do with the camber? My car has always had bad camber in rear comapred to other nsxs with 19s and I was never sure why. Can I adjust this so that I can get my rear wheels to have less negative camber?

Presently there is only limited adjustability for the rear camber. When you lower your car, camber will natuarally become more negative.

My company, AYOTTE TECHNOLOGIES, is presently proto-typing a kit to add +2° of camber for lowered NSXes: Patent Pending. We are presently instaling it on an NSX for testing. It should be available within the next few months.

I would not suggest setting the camber by eye. Playing with the camber will affect the toe settings. It should be set on an aligner.

When you get your kit done be sure to spread the word. That would help a ton of people myself included:smile: :smile: :smile:

Pardon my ignorance but no one is currently making a rear camber kit for the NSX?

No one is to my knowledge.

Contact Chris @ SOS, he had some put together, but never released. http://www.nsxprime.com/forums/showthread.php?t=28558&highlight=camber+kit+sos Look at this post from a while back.

I'm allways available for updates, just PM me and I'll revisit the post with the answer.

The kit will be much easier to install than the SOS method and will be less risk of damage to parts. After performing the install yesterday, I'd say any DIY NSXer should be able to get it accomplished in 2-3 hours time. This first kit will give +2° for $350. The next version will allow much more, but, one, we need to know the interest for gaining more than +2°, two, would the increase in cost, maybe $450, be acceptable for sale.

Sweet!!

I'm in for sure!!!! I run 295's on the back and only 1/2 of the tire is making real contact. When I launch the car and leave skid marks I leave half treads:frown: PM me as soon as these are available. thanks--Brett

 

[Esprit1]

I second that. Please place me on the list also. Seems like I'm running only 1/3 to 2/5 of my 315's.

Best Regards

Same here I rather spend 350 on that then 400+ on rear sets

While camber surely has a part in decreased tire tread-wear and based on just looking at it would be the easy and obvious answer, isn't a lot more caused by toe settings? Toe in/out causes the tire to "scrub" as it rotates, no? I see cars all the time with lots of camber that are within spec and does not severely wear the insides of the tires. Older Zs and ZXs and older 3-series BMWs come to mind.

I'm not concerned with tire wear, I just want all of my tire to touch the ground.

 

[SilverStone05]

so what's better for tire contact? more positive or more negative camber?

isn't within spec good enough for optimal tire contact?

The problem is that lowered cars can not be adjusted enough to get the rear camber within specs, and this causes rapid wear on the inside of the tires.

The toe can be spot on and the camber will still cause the wear issue we have on the NSX when lowered. Those older trailing arm suspension cars (E30 3 series) were a little different animal than a mid-engine double a-arm set up.

I think you need to decide what is optimal for you. I.e. taking turns, you would want more negative camber, how much may depend on how aggressively you drive.

The problem with the NSX is that while it can be adjusted for camber, there is only a limited amount, and if you lower with say eibach's or dali springs as many have, you cannot get it back close to 0 degree camber, (I think mine is around 1.8 degrees of negative camber in the rear). So if you typically drive on the street, i.e. straigh lines then having negative camber will wear your tires prematurely because only part of the tire is carrying the load of the car and wearing down(inside portion of the tire). Some people, including myself swap tires from left to right, at least on my rears, to try and help even out this uneven wear.

I have never heard of a car that benefits from positive camber, but someone can feel free to correct me if I am wrong. And as someone said before toe in/out can wear tires just as fast if not faster than negative camber.

swap tires? as in left wheel to right side and vice versa, or do you mean like flip the same tire on the same rim for the rear?

You cannot flip tires if they are directional, you have to dismount and remount.

As SNDSOUL said, most of the tires they sell for our cars are directional, I cannot think of any that are not. In which case you have to take the tire off the rims and swap the tires. This will put the inside portion(most worn) of your left tire now on the outside(least worn) and vice-versa for the right.


Hope that makes sense.

Just switching the tires from left to right and vice versa (even if they were not directional) would not fix anything, as the inside of the tire on the left would now just be on the inside on the right. You have to dismount the tires from both rear wheels, and then install them on the opposite side of the car so that what was the inside edge of the tread is now on the outside edge.
