Hello everyone,

So I just ordered a pair of j&m extreme lower rear control arms hoping to get some extra traction, the more I reseach them though the more I get told that they don't help that much, all they do is help wheel hop which I don't think I have because when I hit it from a stop the thing just sits there and spins. I run 255 Sumitomo tires to so that probably doesnt help. I will eventually get knew ones, but until then I was wondering what other suspention upgrades is there to help me out (panhead bar, upper control arms etc..). See with my auto i'm making 380 to the crank and i spin threw first second and hit thrid the tires are spinning fast enough that it desides it wants to gear up to 4th and when I hook up finally it drops to 3rd again then it just goes. Hope the control arms will help that, but if not what else is there besides tires. Sorry for the long ass write up lol. Thanks for any help guys.

I don't think lower control arms or any parts will stop wheel spin. The set up of the rear suspension is the key. Has the car been lowered? If so, the geometry of the rear suspension is probably working against you. The critical issue is the angle of the lower control arms, they should rise slightly going forward. If yours don't, look into a set of anti squat brackets they will lower the rear mounting point of the lower control arms. The next concern is setting the pinion angle correctly. There are many good articles to describe this process online. After lowering mine, the wheelspin was aggravating, with anti squat brackets and adjustable lower control arms to set pinion angle this was minimized.

My car has not been lowered, would this still apply to a car that's not lowered?

Your problem is the friction coefficient between the tires and the ground. Going hog wild with the suspension may get you 10% more traction. Nothing will get you a traction improvement like tires/better tire setup will.

With a stone stock suspension and 255 Goodyear Eagles my 2012 hooks up real well. And it is making quite a bit more power.

I’m going to make a guess here. You have those 255 Sumitomo’s on the stock 8-8.5” rims?

I got them on 18x9 Bullitt Wheels. What would be a good tire to get that's streetable durable, that will have good grip?

Well at least you have semi wide-ish wheels (some 9.5’s would be better and 10’s better yet).

The tires I would go with, and the ones I will be going with when my 2012 needs new rubber are the Nitto Invo’s, 275/40-18. They are sized correctly for a 9” rim so the sidewall performance will work like it is supposed to.

They are not “high mileage” tires but they are very, very good for a true performance tire. A friend of mine runs them on his car and I spend a lot of time behind the wheel. I am amazed at how well they grip, how much feel they have, how quiet they are and how good they are in the wet for a “performance” tire. There is no such thing as a tire that does everything well and lasts forever, but these are about as close as it gets.

Good suspension and sticky tires are both critical to maximizing your traction.

Your quickest/cheapest gain will come from upgrading your tires. But ultimately, upgrading your suspension is important as well. UPR's 2010 GT automatic runs 9.90 @ 133 on drag radials with UPR Pro Street suspension and Hoosier drag radials.

I love my Invo's as well. Im running 255-35-20 and 295 35 20's . Quiet and way more traction than stock.
