IMCA announces amendment to rules for Northern SportMod rear suspension

VINTON, Iowa (May 4) – IMCA officials have announced an amendment to rules for the rear suspension of Karl Chevrolet Northern SportMods, which takes effect immediately.

Wording has been added to rules posted on the IMCA website allowing the use of solid safety chains securely mounted to the axle housing. Chains cannot be mounted to any floating device.

“From our standpoint, allowing this chain gets back to how the division and its rules have evolved over the past 10 years,” said IMCA President Brett Root, citing maximum free standing spring height and the upper spring perch. “Short of us writing more rules, this amendment makes the most sense.”

Two factors figured in the decision allowing safety chains.

“We were concerned with springs falling out of the back of cars and the amount of excessive force the rear suspension is putting on rear shocks,” Root explained. “It’s our opinion that shocks shouldn’t be used as a limiting device. Shocks can be used in that manner but it can be destructive and an expense to the racer.”
