You can only choose one control arm per side of the car (Upper or lower) to modify on the front. Left and right front Aftermarket bolt-in adjustable upper and lower control arm ok (must have visible part number), must be fixed in place at the track, must use stock factory holesĬutting of left and right front factory upper and lower control arm (stretching & shortening) ok Car must have original VIN number attached and OBD2 reader must remain in car.ġ.All suspension components must remain stock to make and model of car with the following exceptions: No fiberglass or plastic seats allowed.ħ. Minimum 3" x 36" yellow strip on back of trunk lid or on rear bumper for all rookie drivers.ĥ.
MINI STOCK CAR WINDOWS
Lexan rear windows or Quarter windows allowed. Just because the rules don’t cover a modification, do not assume you can do it.ġ.

All window nets and 5-point safety belts must be 10 years old or newer and subject to tech approval /refer to safety rules section. Just be careful you don't grind so much that itcauses clearance problems between the rocker and spring retainer.All engine, body and suspension parts must be make to make and model to model. This allows you to raise the lifter while keepingthe lash the same. If you need to increase lift, you can shorten the stem by grindingthe tip of the stem. This allows the valve to sit deeperin the seat and raises the tip of the stem on the other side of thehead. This can be done either by installing new valves withlonger stems, or, if you need to make only a small change, by grindingthe seat area of the valve itself. Increasing the stem height allowsyou to shorten the solid lifter, which will keep the lash the same andreduce lift. The locationsfor the lifter and valve for the intake for that cylinder are reversed.For our example, let's say that the maximum valve lift exceeds themaximum 0.450 allowed by the rules. The lifter is on the right side, thevalve is on the left, and the camshaft rotates clockwise. Looking at the cylinder head from the front, the first valve for thenumber-one cylinder is the exhaust. It's easy to recognize one ofthese cams because they will appear matte black. Today, most engine builders use nitrided cams in allracing applications for the Ford motor. Thenitriding process uses ammonia gas and high temperatures to infuse thecam with a ferrous nitride on the surface and significantly increasesboth the hardness and lubricity (how easily the material will slideagainst another). The solution was to borrowtechnology from the F1 sector and start "nitride hardening" cams. Thiswas particularly damaging in Ford 2.3 motors.

This results in some pretty radical camshaft lobes, and when youcombine this with the increased spring pressures necessary to controlthe valves at maximum rpm, conditions start getting pretty harsh. For both the intake and exhaust, anything you can doto increase flow through the speed at which the valve opens, the lengthof time it stays open (within limits), and maximum lift should increasepower. Changing thecamshaft is one of the most effective things you can do whentransforming an engine designed for over-the-road service into a pieceof racing hardware. But the valvetrain, which in many ways has a moreefficient and simpler design than what is found in a traditional pushrodengine, also has its weaknesses when it comes to racing.
