Do you guys know of any good shops who can weld chassis bracing/subframe connectors? Basically, I just need someone with experience doing these things, is a good welder, and has a 4 post or drive on lift.

I've already spoken to Piper Motorsports in Dulles, but their schedule is so packed I've been waiting for 2 months now.

Thanks.

 

Function Tuned.

 

Function Tuned for sure. Dave can definitely take care of the those simple welding for you.

 

Thanks, guys. I'll check with them. I hope the lift won't be an issue.

 

Dave can get my car on his lift.. and it is UBER low.

 

Oh sorry, I didn't mean that. I meant that the type of bracing I'm installing needs for the car's weight to be on all 4 wheels when the braces are welded on, so hopefully one of his lifts can accomplish that.

Anyway, I've sent Dave a PM to see. Thanks again.

 

I love JE. But Fairfax -> Bel Air sounds like a serious hike!

 

what type of bracing is this?

 

+1

 

It's subframe bracing for a Maxima... *pauses for laughter to end* .... but it is similar to the GTSpec 4 point brace that you guys have, only it runs the length of the frame rails and not just mid chassis.

I'm doing it because the chassis flex on this car is pretty bad and it rides like a wet noodle. I really just want a more solid feeling, comfortable ride (short of buying a new car, obviously).

 

No laughing here, is that the setup from Truax Motorsports? I've got a B13 SE-R and have been looking into an identical setup. Let me know how that works out, maybe some pics of everything finished up?

 

Interesting. I would like to see how that bolts up when its finished. Tom Bostic at CT2 was talking to me about building one for my car if I go FI. Still up in the air about it.

 

Yes sir. What I have is the first batch made by Truax. I've just never had a chance to get them on. The newer batches are supposed to be more "refined" in terms of ease of installation, less ground clearance loss, and are powder coated (mine are almost raw steel, lol). They also have 3 point braces available for the auto-xers who want to stay legal in certain classes vs. the 4 point braces that I have. I'll remember to update you, but I can say that the few reviews so far have been very positive. Dan and Sean at Truax have also been great to deal with.

 

Judging from the pics in the GTSpec thread and my limited knowledge of Z33s, your chassis only requires more "localized" bracing, so what you guys have are more like lower tie bars and not so much subframe bracing (but correct me if I'm wrong). Still, it seems that the basic concept is similar: eliminate as much frame flex for maximum chassis rigidity to allow the suspension components to be more effective.

Here's what a Maxima looks like with those on:



It's really the frame rails that are being reinforced. The cross bracing is effective too, but the primary focus there seems to be the rails.

 

That's what I hear about them. They did a group buy on one of the forums and sadly I couldn't get in at the time...looks worthwile though. +1 to you sir for strengthening the Maxima chassis

 

Get that POS outta here.

 

That's Kevlo's car...

But I have rims off a Z, doesn't that count for anything?

 

For chassis bracing, the round vs. square debate still goes on in many enthusiast communities, to my knowledge. All I know is that for basic chassis stiffening (and probably more so because this isn't for a race car) and the types and amounts of forces exerted on the frame, either will work just as well. I'm no expert by any means.

 

Solid square bar stock tensile strength is far less than tubular stock (unless it's Ti or something LOL). Round tubular stock is also lighter being hollow. Pipes and tubes, that kinda stuff is my bread and butter all the bolted joints decrease the strength even further as the bolts under lateral force over time will egg out the steel plates if they are even positioned correctly to operate functionaly.

 

I understand where you're coming from and will not (and cannot) debate that with you . I'm just saying that for supplemental chassis stiffening on my daily driven Maxima, the square tubing should suffice. I won't even be using those x-braces (which don't look very sturdy anyway), only the bracing on the frame rails. I appreciate the feedback though.
