Nice looking car may get one this winter
whats the deal with puting the LR shock behind the rear end on the slick?
Ok if we’re talking about modified’s Or late models , you would take the traction shock off the LR front and just run with the coil over shock behind . No need for a traction shock cuz it will have grip on a rubbered up track. The traction shock is just to control wheel hop , your tires are more likely to hop in a tacky track. When the track slicks over , car should be hooking up and be up on the bars. Unless you don’t have much motor , like a 602 or a 604 crate . Than I would try it with and with out. Also trying running a 609 gear with a baby motor , you will find that you will be passing car off the corners . But on the straight away you’ll be fighting them off , but if your a consistent driver and can hold your line you’ll win races.
Modifieds I race and imca car here in AZ where the tracks get pretty slick and I here’d about your car and thought it was really cool Trying to learn about these mods this is only my 2nd year in one iv already got a win
