Yes, these should work with the Brembo Performance pack calipers/brakes. The 18x5 size was designed more or less for them. Let us know if we can help get you going on a set. https://www.lethalperformance.com/weld-racing-ventura-drag-s155-18x5-inch-5x114-3-bolt-wheels-s1558c067n23.html

If you are looking for just a stock replacement, those will be fine as the mounts are the same. If you are looking to replace them and get some more alignment options, I recommend going with camber plates. I have them on mine and I was able to dial in the specs I needed for the springs so the...

If you are running them with stock everything else, you won't hear drone. Even if you delete the resonator. It will be louder for sure but no drone. This style of muffler was designed not too with the factory cats. If you are looking to pick up a set, let us know if we can help...

Theirs plenty of tuners who have said this and can get you all the data. I have seen it on the dyno many times and have had people complain the car feels slower or they didn't pick up the power they hoped for. This is why people with cats have noticed a slight increase in trq. Not peak hp and...

Headers in general are a nice touch. While some can net more hp over trq, they can improve the performance. Depending on the material, flow pattern, design, spike used in the collector, and the collect location, you can see different power curves. Most headers can net 20-30hp and about the...

We offer a couple different kits for something like this using STEEDA and BMR. Both will work great and get you in the direction you are looking to go. From there, it's just shocks and if you want to solid the bushings up more. If yours is a manual and you are gearing it more towards drag...

Mine will do it if I am on decel in sport mode with the Borla S-Type and their matching resonator (Touring) into LTH Exhaust headers. Bring mine doesn't have active, these are the headers I run which with the factory active sounds awesome IMO...

I wouldn't go lower than a 1" spring. That is what I have on mine and a 28" skinny fits. But any drag spring will work. Just have to make sure you get the correct on for magnaride or regular. We work with tons of spring brands so let us know if we can help...

Sadly as others have said, 2-piece rotors do cost a lot more. No way around it either. Any replacement 1-piece will weigh about the same. It's just the material they use and if it's zinc coated that will change. With that said, we work with tons of brands so if you need help, let us know...

Last day to save on Whipple Superchargers! Don't miss out on the biggest sale all year!

So Borla directly makes the Resonator for the Borla catbacks. Ford Performance offers one but it's the same. It only fits there catback which Borla makes. Now, if you go with a Touring style exhaust which I run on my 18 (non active) it sounds amazing even with headers. It's louder but not...

Quick question, are you looking to add headers soon? That right there will give an option for mufflers or catbacks
