Aftermarket windshields often weigh much less than the old factory windshield, and it's high up weight which is double good to remove.

Also, focus not just on weight removal but where the...

Call Riley Curtis at Lynchburg Nissan. He usually has a stash. 800-443-2117

No need to "fix" anything- it'll loosen upon it's own :) Bottom line- don't fret over getting big preload numbers as it doesn't seem to help anything.

Hot tip on setting up preload on a Nissan R180 LSD: don't do anything! I spent a lot of time setting them up for 105 ft-lbs of breakaway back in the day, which was the accepted hot tip according to...

Just ante up for a Quaiffe, they're only about $1200. :)

We had 2 LSD units that we swapped between about 4 gearsets. I think we eventually sold one of them and then just swapped it into whatever...

Step 1: Buy Factory Service Manual.
Step 2: Do what it says for a stock car.

You can ignore those two steps if you have tons of money for dyno testing, in which case you will discover that in the...

Add Z front diff mounts to your letter next time. I'm sure they're just waiting for a big enough request.....snort.

Saves even more money if you never replace them. Now if you got an RX-7, which eats plugs even in street motors, then you might want to budget for regular plug changes. But honestly, bend the...

That ain't actually the food ledge. That vent pipe feeds the food ledge, which is the metal stamping on the outboard side of the hood line, under the fender, welded to the inner fender stamping,...

That was according to the current owner, Bobby Bitterman in AL. The car now races vintage, but is still in IT trim, tires, and the Sunbelt IT motor that was sold with the car. Not sure what if...

That, gentlemen, is a man who don't let ego get in the way of good decision making.

Higher rates are ultimately faster on paper because the aid to roll control gives a better contact patch...

That.

The natural frequency of the suspension springs for the rates and dimensions commonly used on 240Z's is inconsequential. Now you want to talk about spring harmonics when it comes to valve...

Spring Rate, K = (G*WD^4)/(8*Ne*Davg^3),
where G = 11,000,000
WD = wire diameter
Ne = number of effective coils
Davg = average diameter (ID+OD)/2 or OD-WD
You have...

We did use stock junk yard harmonic balancers, and in fact I used the factory "with air conditioning" pulley attached most of the time. Don Potter was a big proponent of as much front end mass on...

Riley should have told you that clarkcopperheadgaskets.com has a custom fit L24 gasket designed by yours truly that he can whip out in just about any thickness.

We had an engine that ran all...

My engines didn't leak, and they didn't blow up, so never had any fire issues. Wrap is WAY better at keeping the heat in than any coatings. Although I did a ton of header testing we never did a...

Ron and Paul win the "most likely not to fake oneself out with funny SU damper oils" award. 20wt, commonly found in the two place they mentioned- motorcycle fork oil and Redline.

I've seen a lot...

It may be a start for an EP car, but otherwise, "its won a local autoX". Doesn't look legal or competitive in any SCCA class....

Now don't go interjecting common sense into this.

Guess I'll have to dig up my old "OUST55" license plate....

Werd.

We learned to never race the Z in the rain. A) you get wet, B ) backmarkers hit you while you're lapping them, C) even with a working heater core the windshield fogs up, D) its hard to shift with one...

Way to go Paul!:happy204:

Nothing beats the stock tank for location. You'll want to put the cell as low and to the right as possible. I think the GCR still gives you 6.5 inches from ground to bottom of tank. Our 15 gallon...

Never heard of a diff bearing going bad. Sure it isn't the center countershaft bearing in the tranny? That's a common occurrence.
