Supermodified Tech: How to Adjust Ride Height

The Nuts and Bolts of Adjusting Supermodified Ride Height

By Group R Motorsports owner Bob Bogwicz

If a super uses torsion bars to hold up the corners of the racecar, the race team uses an adjuster bolt to change ride height.

For this weeks pit-side chat, we are going to discuss the ways that ride height is adjusted on the supermodifieds that hit the pavement at Oswego Speedway.

On today’s supermodified, ride height can be adjusted in one of two manners: the coil-over adjuster nut or the torsion bar adjuster bolt. Continue reading Supermodified Tech: How to Adjust Ride Height

Supermodified Tech Knowledge-How Shampine’s Radical Offset Revolutionized Supermodifieds

By Group R Motorsports owner Bob Bogwicz

This concept is what makes our brand of racing so unique, exciting and fast!

Group R Motorsports logoIt has been almost 40 years since Jim Shampine introduced what has become the prototypical supermodified: the radical offset 8-Ball. What made this racecar so unique is that Shampine took a concept that many builders were toying with since the early 60s and took it to a winning extreme. That concept is offset.

I lied to you. All of you. I said in last months installment of Supermodified Tech Knowledge that we would discuss stagger this month. Well, we’re not. I lied. We’re going to talk about fuel cells instead!

The reason for the change in topic was quite serendipitous. For those of you who race dirt, that means “a pleasant surprise”, ha ha!.

As I write this, I’m in the beautiful state of Oregon, installing a machine for one of my customers. Even though these trips keep me away from building our new supermodified, I’m always working on the project one way or another.

So, while searching on my computer for a needed document, I happened across information about fuel cells. It piqued my interest because I am in the process of defining the configuration of the fuel cell for the new car. The document was from a company called Fuel Safe. Not only had I heard of them before, but they were recommended to me by none other than Joe Hawksby of Hawk Jr. fame.

Just for the heck of it, I typed in the web site for Fuel Safe and lo and behold, they are in Redmond, Oregon! So, I naturally shirked the current responsibilities of my customer and headed to Redmond. Continue reading Supermodified Tech Knowledge-Why Race Cars Use Fuel Cells
