I'm not sure what formula they use to stage them, but it's G35, 350Z, M3 at the start. the finishing order is either reversed or the M3 just passes them both, I forget. the lap times they show at the end have the M3 as being 2+ seconds faster than the other two which is no surprise. there is really no comparison between the Nissans & the M3, unless you start to get into silly "what if" scenarios when you mod the hell out of the Nissans in an attempt to spend the $60k that the M3 will likely cost.

It is the tension that the rubber squeezes against the metal that keeps the bushing in place. It is important that any lube used not react with the rubber over time. Silicon is inert in that regard. Various soaps may have ingredients that will react with and degrade the rubber, making it softer and less cohesive. Trapping water against the metal shaft can promote surface oxidation which will both wear off and abrade the rubber, resulting once again, in less contact pressure between the bushing and the metal. A softer rubber contact surface will have less friction, thus more likely to slip as the control arm tries to rotate in the bushing hole. While inserting through an unlubricated surface can cause abrasion of the contact surfaces. These little tears can deteriorate and tear further under pressure over time. In the past, I recall some sort of 'officially recommended' factory lubricant to coat bushings with while installing them. Would someone with access to possibly a 70's era factory manual or parts listings like to look that up? I imagine someone no longer with us would have known the answer right away and probably stocked the item too. In any case if what you do works for you and doesn't cause other problems along the way, do it. ymmv, 'jk ------------------------------ Date: Tue, 24 Jun 2003 14:39:32 -0400 From: "Dorffer, Rich" <[EMAIL PROTECTED]> Subject: [uuc] Cleaning filters > When Jim C first started advocating ITG foam filters, his recommended > cleaning method was kerosine baths.

The more it filters, the worse it will flow (duah). Not necessarily, just because a filter is in place, doesn't mean flow will be worse as a properly designed filter could possibly funnel the air better. And, filtering efficiency isn't a direct relationship with flow. Michael already posted a comment about the potential capacity of BMW intakes which I would have also stated. Any of the air flow engineers can correct me but that has been my understanding. Regards, Rich - uses ITG filters for a few reasons although I believe it is tough to beat the flow and filtering efficiency of stock paper elements. ------------------------------ Date: Tue, 24 Jun 2003 14:39:20 -0400 From: Dave Bell <[EMAIL PROTECTED]> Subject: [uuc] Pre-purchase inspection shop in Palm Springs / Palm Desert?

You have to use gloves with both the cool and hot parts, but the temperature differential is enough to slide the hotter part over the cooler one. I'm confused about leaving parts out in the "snow". Is that a really cold stuff like ice cubes? My refrigerator makes those.

Any slippage there will wear the bushing. Soap, water, or even kerosene are suitable lubricants. Silicone will remain slippery and may allow the bushing to slip on the control arm. This is not a catastrophic problem, but it should be avoided if possible.

It's freezing the arm that doesn't make sense. To ease a press fit you want a big temperature difference. Cooling both doesn't make sense. jkerouac wrote: > re: why freeze the bushing? was E36 bushing install: > > By freezing the bushing, it becomes harder and less flexible. > Thus more slippery.

You can buy it from the drug store usually. It is a pure soap and has been used for many years to lubricate the rubber bands used as motors in model airplanes. it is non harming to rubber. There is also a product called "tincture of green soap", basically green soap and alcohol. This may work better as it is not as thick and may evaporate in a more timely manor.

This is all very well and good but BMW designed the control arm bushing rubber to "stick" or adhere to the control arm, the control arm isn't supposed to spin freely or move within the bushing. A wise, not-so-old, BMW sage educated me on this one. I installed my solid E30 M3 bushings quite easily on my control arms without any special technique aside from water (no soap or other lubricants) and the BMW control arm bushing tool.
