Nissan Skyline Spare Tire and Interior Trunk Parts

R32 GT-R Spare Wheel and Tire

The lowly spare tire.  An R32,R33, and R34 GT-R has a space saver spare located in the trunk. The OEM spare will clear OEM brakes, but if you have aftermarket brakes, you should take some time to see if the spare will work. Check out your spare tire air pressure. Also, its probably time you replaced that tire. Even though its probably never been used, its aged out by now.

The Ultimate guide to Suspension and Handling Part 1, Wheels and Tires

The Ultimate guide to Suspension and Handling Part 1, Wheels and Tires

 

 MotoIQ's Mike Kojima posted the first part of their ultimate guide to suspension and handling.

Horsepower is sexy and chicks dig it, at least a lot of meatheads think that way. Making horsepower is relatively easy. A lot of competent people know how to make power, lots of it. Until drifting became the rage in this country, handling and cornering prowess was for geeks, the road racing elite and autocrossers. Handling was for dweebs that raced around cones in parking lots, or loners prowling canyon roads at night, not for cool people in the scene.

How to tune a car's suspension was an unknown art in the world of mainstream performance, simply because most people didn’t care about handling. Most people emulated the world of road racing by making their cars low. Low was cool, low was handling.

 

Mike explains some of the basics on tires and wheels, and what people should look for in wheels and tires, obviously more slated to track/street usage than bling.

I am looking forward to the rest of this serious. MotoIQ is full of great tech, you should check it out.

Racecar Engineering December 2007 - Ferrari tire gas mixture

Racecar Engineering is the automotive magazine you probably have never heard of. They carry them in some Barnes and Nobels, but they are a little hard to find. Its a UK based technical magazine about the racing industry. Its expensive - about $9.99 an issue, but it has some really great information. More than most people would ever want or need, but if you are really into competition, this is a magazine for you. Lots of up close pictures and analysis of race car competition.

The December 2007 issue covers some of the technical information that was passed from Ferrari to McLaren in the spy scandal from last year. One part that was interesting was the use of specialized gases in the tires of the Ferraris. Most people use air in their tires , some race cars , even the new GT-R, use nitrogen in their tires. What Ferrari found out though , was by using a combination hydrofluorocarbon (HFC) - based mixture specially made for use in racing tires. This mix greatly extends the performance of the tires over a number of laps. For instance in the Ferrari testing after 23 laps , tires filled with air had about 40% of the performance of a new tire , where the HFC mixture had 80% of the performance of a new tire.

The mixture of gases also allowed for a much longer tire life before bursting. Where nitrogen would last for 64 minutes before bursting , the gas mixtures allowed the same tires to last from 94 minutes to 103 minutes.

Very interesting . Has very little to do with street cars, but in other series , we might start to see them using this new mixture, or a combination of mixtures in tires to increase performance. Having run in a series that used a spec tire , over a 50 minute race , if given the ability to get this gas mixture to put in the tires , I think most of the racers would use it.
