I was told to get LCA's and a PHB *adjustable* when I get 325/50/15 tires on my car with a 15x10 wheel. How will these components help? Will they stop all the rubbing that's going on?

 

they won't magically stop it.

but if the car is lowered, the axle is offset to one side. the adjustable phb will allow you to recenter the axle.

the lca may be more compact, which will give more clearance from the side of the tire to the side of the lca.

 

The car is not lowered, I just have larger tires. I keep hearing that if you run larger tires, the LCA's and PHB will help tremendously.

 

If provides the ability to perfectly center your rear tires in your fenderwells.. Thank you and good luck

 

Adjustable LCA's can be thinner like stated, and help forward and backward alignment. PHR helps the axle be centered side to side. You shouldn't need a new PHR if your car isn't lowered.

 

The tires you are looking at are 27.8" diameter. You may need to move the axle assembly forward or backward to keep the tires from hitting the edges of the wheel opening. I run 28" slicks, and had to move the rear axle back about 1/4" using adjustable LCA's. That kept the front edge of the tire from hitting the metal on the front edge of the wheel opening/quarter panel, when the tires grew as trap speeds went over 125MPH. You will not have growth problems with radials, though.

As already noted, with the correct offset on the wheel, to keep a 325 "section width" tire under the fenders, its necessary to exactly center the body side-to-side, to minimize the chances of the inside edge of the tire rubbing the inner fender, or the fender lip cutting into the outside edge of the tire. That is accomplished with an adjustable panhard rod.

Simply installing a non-adjustable panhard rod and LCA's will not offer a lot of clearance advantages, except that firm poly bushing or rod ends will prevent the body from moving when the bushings are being compressed, either under hard cornering loads (panhard rod bushings) or a hard launch (LCA bushings).

 

Thank you, very much. The ONLY place it rubs is that little inner fender piece on both sides, and above the bump stop, on those lips. I think I'll have to bash it in more, and hopefully the LCA's and panhard rod will help. I can tell the difference in clearance for the passenger and drivers side, the drivers side has more.

 

My rears are a 51mm offset. Is that what I should have gotten with the 15x10 Weld Prostars?

 

I have never seen Weld spec "offset".... they generally spec backspace, and with a 15x10" wheel, you need a 7.5" backspace. Using my backspace calculator spreadsheet, it calculates a 50.8mm offset for that wheel, so it looks OK.
