Replacing steel fasteners with Ti versions is for those with burgeoning DIY budgets and or bragging rights, and best suited for cycle weenies where weight savings can make a difference. Spend your money elsewhere for more effect.

Bragging rights it is. Those carbon bolts sound epic!

I don’t think you’d be that worried. There are at least three fasteners for each critical joint. So it would be hard to miss if they started to fail.

+1 what Sherwood says....
If you are doing this for appearance that’s fine and a lot more cost effective to replate the hardware in finish of your choice and retain strong steel hdwr.
IF trying to reduce car weight, TONS of places to do and a lot more cost effectively achieve such...
Have fun... many ways to skin the cat you seek to do

As long as you're chasing weight loss on the engine, get yourself a magnesium case breather cover and magnesium upper valve covers? The upper valve covers will typically require some flattening on the grinder table..........

Don't forget to use some M8 titanium nuts on the valve covers and engine case peripheral studs?

The amber tins save about 2.6 pounds, or 41.6 ounces, or 1,179.43 grams. The Ti bolts that someone emailed me a link to should be a nice touch.

My Ti fasteners finally showed up from who knows where. I had a chance to weigh them to get actual numbers. I used the normal steel washers for the comparison since they are under 1g each. They are about 1/3 the weight of the typical steel fastener. So about 1/3 of a pound when you combine all 39 of the M6x10mm pieces. Is the juice worth the squeeze, YMMV http://forums.pelicanparts.com/suppo...ool_shades.gif

I'm back... with more data.
I'm not sure who mentioned nylon fasteners but... thank you. They are .5g each. So I am going to run them in a few areas for a few weeks and see how they hold up. I have some concerns about the heat having a negative effect but they definitely are significantly lower weight. And as an added benefit, they won't rust! This pic is the equivalent number of fasteners while maintaining the same weight...

Hey how'd the nylon fasteners work out?
