Are the parts for the 5.0 R better than the 3.0 S I need to upgrade my suspension & tires to stop fishtailing when I do pulls from a dig with no DSC

You need better tires.

agreed, the P zeros prone to break traction, I'd try tyres first. I've tried michelin supersports which were a massive improvement and a better ride, the ps4's were better still

What tires are you currently running? Like everyone has stated so far, better tires would be the way to go. And if you still are fishtailing, then you need to control that right foot of yours.

DWS06 305’s in the rear so yeah I know I need ps4s tires all around and I have ridiculous Nitto Motivo in the front so I’m a fix that cus the power my car is putting down vs the power it actually has is definitely not the same.

I street race my car so the right foot is going to stay down lol

I read somewhere that putting the 5.0 rear suspension on the front of the 3.0 and then welding the rear suspension helps with fishtailing.

was looking at getting the DWS’ as my next tire as I need all seasons so not thrilled to read that.

Since you street race, you already know that spinning doesn’t make you faster! Lol. Gotta feather that gas pedal

DWS06 are great all-season tires just not for racing but also I do burn outs a lot so they are worn down too.

good to know. have any experience with the Pilot Sport A/S 4?

my friend @Nycikku has them he would be a better person to ask then me.

hopefully he sees this thread and responds. I’d like to read how they compare. Will be doing some googling on them

if you buy a rear wheel drive car that has 340 to 550 bhp then expect to get oversteer. just don't be so heavy footed on the accelerator pedal and remember that high performance tyres do not grip very well below 10 or 15°c..
