I was just looking over some of their regulations quick, i saw a few things that may an issue to some. So i figured id just make it known now, so people dont get their hopes up of hitting high MPH numbers with how thier cars currently sit....

ll-5 DRIVE HUBS: Above 150 MPH, any vehicle equipped with a non-retained axle bearing (non-Hotchkiss type rear axle) assembly must incorporate an approved hub to prevent loss of a wheel in the event of a rear axle failure. Semi or full floating rear axles are sufficient. Late model rear ends using “C” clip axle retainers are NOT acceptable.

All closed cars between 150 and 175 MPH must have a 6 - point roll bar. All closed cars over 175 MPH must have a full roll cage. All open cars are advanced one bar / cage category over closed cars. Any individual wishing to enter a vehicle which deviates from these rules MUST contact the ECTA 45 days before the event for approval.

II-8 WHEELS: All nonferrous wheels on which lug nuts would come in direct contact with the wheel must have a 1/4” thick steel retaining plate or larger o.d. heavy gauge individual washers under all lug nuts. T his does not apply to spindle mount wheels. Magnesium wheels are NOT recommended and, if used, must have an initial Zyglo certificate and stamp. Wheels are to be re-inspected if any adverse conditions arises. Inspections made with tires mounted are accepted. It is recommended that tire pressure used on two piece wheels does NOT exceed 60 psi., or manufacture’s specifications.

Vehicles with tires having a diameter of 30” or with wheels over 17” in diameter must use a wheel manufactured for racing or reinforced as below. Wheels must be attached with at least 5 studs having a minimum diameter of 1/2” and 1” hex nuts.

In either of the previous cases, wheels must be manufactured for racing purposes or reinforced as follows: By welding the entire area of attachment between the rim and the center section of either the inside or outside of the wheel. Alloy wheels not certified by the manufacturer for racing (i.e. factory wheels are not allowed above 150 MPH. Also , no closed end (Acorn type) lug nuts are allowed.

Wire wheels designed for automotive racing applications such as Rudge or Dayton are allowed. OEM wire wheels are allowed only in classes under 200 MPH provided the center section is adequately reinforced. Motorcycle wheels not designed for automotive applications are prohibited.
