Undercarriage part replacement

[MONKEYSOCKS]

Hi Guys, trying to replace old for new on my 350z, it's going into Tarmacsportz in January. Is there a better aftermarket replacement for the rear subframe support brace? Or do I have to just order a new one? I've ordered ultra racing w brace and ultra racing front brace, are there any other braces that I need to be aware of? Because I've only just found out about this one! https://share.icloud.com/photos/057jknR0jU03NYM1rXDzp2VjQ

There's no aftermarket version of the brace you linked the photo of. 

 

Other than the ones you've already replaced, Ultra Racing only really do other aftermarket braces which aren't OE replacements. 

 

Member Stays / Kidney Brackets are likely to need changing if you haven't done so already, OEM is the only option for those. 

 

If you're trying to freshen everything up, this one also tends to be rusty, it goes between the fuel tank, some people just remove them as they aren't deemed structural:

Hi mate, yeah I've got new rear kidney brackets on order, and getting rid of the board assembly, whilst the works being done. I'll have a look at the state of the subframe brace and go from there. Cheers for your help.

I'm also going to get whiteline arbs and droplink kit. Is there anything else I should possibly look at whilst the exhaust/cats are off? Slave cylinder etc?

I had around 10 of these available 8 months ago, but would have to check if I have any left.

 

These are refurbished preowned OEM.

Guessing the cat brace needs to stay on for cobra hfc's? Heard they'll crack with out it, Is that right? I know people who run art pipes don't need them, but i would imagine it's different with Hfc's?

The cobra HFC have the mount allowing you to retain the oe cat brace. You don't need them so much with decats or art pipes as these are much lighter than cats/hfc's.

Okay, 🐻 with me.   Thought I could replace the stock anti roll bar with whiteline kit included drop links, just in terms of removing rusted oem parts. However after a quick chat with Tarmacsportz they've said it can't really ride at stock height should I change to whiteline drop links, so would have to run oem drop links with whiteline arb at least until I eventually plan on dropping the car height . I'm sure I've heard somewhere that aftermarket arbs will chew up stock droplinks though? Is this correct?
