Scraping Sirimoto subframe brace, worried about subframe damage.

[Physical]

A few weeks back I put on the Sirimoto subframe W brace and rear chassis links. The W brace is the lowest point on my car, and as such I've bashed it more than a few times. The brace itself is dented and deformed, but I'm worried about bending or warping the front subframe, or even sheering off subframe bolts. Is there any chance of that happening? The brace is aluminum so I assume that'll break before any subframe damage occurs.

Got under the car today and took a pic just to showcase the damage. She really takes a beating.

thats the trade off on these man, only solution is to raise your car. personally i would just take it off cons outweigh the pros

This was my exact fear about installing the brace. Looks like my fears weren't unfounded. Sorry to see the bad experience of what otherwise looks enticing.

Honestly the improved stiffness with the kit (included the rear chassis tie links) is incredible. I'm not going to take it off until it's completely bashed in or outright broken. The highway stability is vastly improved, and cornering feels noticeably tighter, think less steering input for more actual movement. It's a great kit, but with a lowered car, there's obviously some clearance issues. This isn't SiriMoto's fault in the slightest, it's a great kit, as long as you don't mind dragging it over everything on the road.

After doing some thinking I feel the brace is what's likely to break here, not the subframe bending or the subframe bolts sheering off. The brace is soft aluminum, it'll deform and eventually break if I keep nailing every bump on the road.

On a car at stock ride height, these bars are fine. The Sportlines he has lower the car like 2 inches.

2.3" in the front 2.5" in the back, I do drive around with a ~80 pound floor jack in the car along with all my tools though, so that probably contributes to the pretty hefty drop in the rear.

Hello, all.

Does anyone know if this uses the same forward mounting points as the Type R subframe brace? I have the Type R brace, yet to install, but really like the idea of putting the Sirimoto one on.

That wont help, extra weight is never good. Also carrying around a full size matching spare ?

Not only hurting your brace, but that wxtra weight slows the car down.

Bummer deal about the W brace. I just installed my rear braces and love them! After installing I took the car out for a spirited drive. I could instantly feel more of a connection with the rear of the car. Driving over speed bumps in the rear were less bouncy, driving around corners feel tighter fast or slow. I took a suggested 30 mph on ramp curve at 65mph (normally I take it at 50 to 55mph) and it hugged the inside line with ease. Usually at 50 to 55 mph I have to fight it a little. Super easy install definitely worth the money! I'll be installing the W brace next (soon) and hopefully with stock ride height, I wont have this issue. Check out my install video on the rear braces!
