Does this fit a 2006 Mustang GT Convertable?

Texmex1970 Year: 2006 Model: GT

  • Texmex1970 No, not for convertables. Convertables have different frames and some already include sub-frames. Duke 7

Jacking point Can these also be used as a jacking point instead of the tiny holes in the plastic molding? I noticed that Hotchkis offers such a setup for the 2011+ coupes and am curious to know if these would be suitable for that as well.

CurbRash Year: 2012 Model: V6

  • They are not design to be a jacking point, but, they are strong enough to be used as one. You can also modify them by welding a plate to be used as jacking point.

Will these subframe connectors work with my Boss's quad exhaust? Will I have to permanently remove the quad exhaust from my car for these subframe connectors to properly be mounted or will the quad exhaust fit around them?

    These fit just right, with the option to bolt or weld them on, you can choose what it right for you. The Difference is noticeable right away when you get it out on the road I personally just welded mine in place after I bolted them up. These are a must have for anybody wanting to get more power to the ground.

    There is a lot of well thought out engineering in these connectors.

    These connectors tie into the existing frame in four locations, twice as many as most others. The welds are beautiful, as is the powdercoating. The fit is also extremely precise, especially for such large pieces. On my first test drive, I soon noticed it was not "scrubbing off speed" with body flex in turns. My GT is more fun to drive as a result of being tied together with these connectors. They are an excellent improvement for my GT.

    CE Subframe Connectors

    Very pleased with this purchase. Absolutely makes my '08 GT feel completely different...in a great way! They tie the front and back together and eliminates the body twist, which is of course what they are supposed to do. Everyone should own these. My mechanic told me they were a bit of a pain to install and he had to remove the wind deflection devices from the bottom of the car in order for them to fit....but that is more than a good trade off. One of my first mods along with adding some power w/FRPP CAI, Magna Flow Tru X-X pipe, Flowmaster Outlaw axle backs & a SR strut tower brace. Good power & the car handles awesome. If you're on the fence about getting these....do it! You won't be disappointed.

    Must Have.

    After hours of research I stumbled upon these sub-frame connectors. They were a pain to put in by myself on jack stands but totally worth it in the end. However after some measuring I found some of the holes were off on the drivers side but no worries as I just egg shaped the hole and they went in. As for the aftermath of the install, the car does not even feel like the same car. I feel like the car is now to slow for the chassis and feels like it needs more power. turbo perhaps...

    Had no idea it would be so good!

    I read the ad for these subframe connectors and thought I'd give them a try. I told myself anything will be beneficial. However, after having them installed I was actually amazed at how much more HP I felt go to the wheels. My KR definitely lunchs much better. I will say I expect to see the overall results get better after I replace my rear tires, so I can't wait to test it after the new tires. I did notice after this installation the rear end launches straigther, but with tire tread almost at the tire marks and with more HP at the wheels the tires just spend big time now, but the rear end keeps straighter MUCH better.

    No Bolts

    This product arrive and the box was in great shape, After opening it up it had NO bolts or directions, Just two subframe connectors that weight alot but look amazing. AM should inspect what they ship and Weights of items should be listed on there pages, it would help us order lighter items.
