Rear Subframe questions..

You can use after market lateral links and trailing arms with your stock sub frame... I see no advantage to going to the Gen 1.5 or 2 sub frame. Not to mention I'm willing to bet a lot that its not a direct fit... in other words, a lot of work for nothing. The reason they likely won't fit, the varying width between the 2 gens would most likely result in different spacing between the bolt holes and/or the guide pin holes. The likely hood that all 6 holes line up is slim to nill. In addition to this, and I may be wrong, but if you used the gen 2 sub frame and gen 2 arms, I'll bet they are too wide, so you would have to use custom shortened arms.

Held Motorsports and BMR make the after market links. Its my opinion that the Held arms are a better deal. Couple hundred bucks less but you have to supply $5 worth of grease fittings. :willynilly:

I don't know what everyones problem with the jackpad is... mine is fine, never ever had a jack slip off it, and I have even had to put a piece of wood between it and the jack to get it higher, still no slipping off the smooth piece of wood. :dunno:

This is the 1 and 1.5. It looks like the lateral links are the same size. The only difference is that it has a cleaner/better design. I was hoping I could just swap it over when I put on my aftermarket lateral links. I know it would be unnecessary but I just simply want to upgrade.

It can be weaker because the monoleaf isnt being supported in the middle. I'm sure its plenty strong for coilovers.

 

I see no problem in running that, but I havent had my suspension off yet.

Stick with what you have. You will not gain anything at all by doing this, investing all your work into. Everything that can be done to the Gen 1 can be done to the Gen 1.5 and then they basically become the same cause its the same parts....

I just had my gen1 subframe powdercoated and looked into exactly this issue. A gen 2 definitely won't fit. The gen 1 has bracing for the monoleaf and associated clamps/pads/bushings, and in my opinion is stronger as a result. I've got the red BMR lateral links which, despite being way overkill, look pretty cool when contrasted against a black subframe. They bolt right up un a gen 1. Lateral links and rear trailing arms are identical across all generations.

will a Gen 1.5 rear subframe bolt up to a gen 1? I was under the understanding that gen 1.5s lateral arms were tubular and lighter and then I can get coilovers.

 

If I'm not mistaken Gen 1.5 and Gen 2 have more in common with each other than Gen 1... So that would be a negative. The only gain I could see coming from this is brakes, but to be completely honest, why not put the work into mounting f-body brakes rather than mounting a newer Gen sub frame.

 

I have to agree with mdelorie about the strength. Even just the shape of the Gen 1 lends it to having more strength over the newer gen frames. Add to that the bracing for the mono leaf and I think any custom gen 1.5+ swap would be more of a down grade.

 

FWIW, I have the Black Held trailing arms and lateral links, I love them, they might not be as flashy as the BMR ones but I don't care, they still look and work a damn sight better than the stockers. I paid $350US for all 3 sets of arms and had to supply my own grease fittings ($5), The BMR arms come with grease fittings for $520US... the choice for me was a no brainer!

NO they will not swap by any matter of reason.

 

 

IF... the jackpad is your BIG problem... it is removable. take it off, find someone with a welder.. pay him alot of money... and have him add a piece of metal that will sit in the hollow center of your hydraulic jack. You are using a REAL Hydraulic floor jack and not a OEM scissor of hydraulic bottle jack, right????
