The Shop Burned Down


This is an ongoing compilation of the 3-letter spring codes for C4 Corvette springs, typically the only way to identify a spring when off the car.  The code is stamped on the spring near the end.  This chart started off as part of my personal notes, and is FAR from complete. The data appears raw/messy because that is the way I read it off the carfiche, and I wish to preserve it as-is.  But I hope others find it useful.  Please email additions or corrections to me.  Disclaimer: informational purposes only.  I'm not responsible if you buy the wrong part.

Corvette C4: The Rear Suspension

Image
Your C4 Corvette has, or maybe once had, a great suspension. It could very well be worn out by now though.  C4 Corvettes are old cars and the parts have started to wear out. It's not that any one item is really bad. The problem is that all of the wear has added up. A little bit of wear in a lot of places means you have a lot of total wear. It's a cumulative thing. You may not even notice how worn out things are since you've probably never driven a perfect C4. Your Corvette seems perfectly normal to you even if it isn't. You just assume that all C4 Corvettes drive the way your car does. One of the reasons aftermarket parts seem to make such a huge difference with older Corvettes is that aftermarket parts are generally used to replace worn out factory parts. People put some new aftermarket part on their car and extol the virtues of that part. They would have felt the same difference if they had used a stock GM part.  New parts make a huge difference whether they are OEM o...

Hi Tech Coatings

Thanks to the Department of Defense and NASA we have an entire family of chemical surface treatments that can be applied to various engine components. Our tax dollars have made all of this possible.              Most of the cutting edge developments in both F1 and NASCAR the past few years have been in ever more sophisticated coating technology. Even after all these decades coatings remain as the cutting edge of engine technology.             These coatings are not just about reducing friction. C oatings won’t make a measurable power difference unless the motor is turning over 6,500 rpm. Thermal barrier coatings and dry film lubricant coatings though don’t need to be spinning high rpms to be beneficial.              High tech coatings will though make a difference in three areas.        Increased thermal efficiency of the engine   ...

Garage Fires

If you set your house on fire you’re going to have some issues with the family. You may have to give up on cars and play a lot of golf. That’s just one reason why you need a fire extinguisher in your garage. The very first thing you should do if you set fire to your garage is to call 911. Do that before you even grab your extinguisher. Next make certain that every member of the family is out of the house. Your family is a lot more important than the Lotus XI that’s on fire in your home garage. Human life is always more important than property. With the fire department on the way and the family standing on the front lawn you can now reach for the extinguisher. Types of Fires: There are five different types of fires. We can rule out cooking oil fires in your garage so that brings us down to four. Class A: These fires involve ordinary combustibles  such as  wood, paper, cloth, trash, and plastics . This is your basic trash fire. Class A fires always leave ash when the fire is ov...
