Hey guys here is the new custom design I am going to be getting done for my car. The SFCs will be made of square tubing instead of round tubing and they will be made from chome moly. The stage 1 tubing that runs the length of the frame rails and welds to them at 3 locations will be 1 in and the cross bracing will be 3/4 in square tubing. Instead of being bolted together the center section will be welded together and bolted into their box holders.. I will explain those later. So the center section should still be removable yet this design should provide a better more stable fit.

I am going to be adding 2 additional lateral supports as you can see in this picture.


I said to the guy try and make them as close to the ends so that they connect at the tabs if you have the clearence to do so but if you dont move them in closer and closer to the center untill they clear.
More like this


This should add some more lateral support but the biggest problem with the old design was the way the bolts connected to the tabs thus instead of tabs boxes are going to be used. If you remember I am using square tubing with capped ends much like this


Those square tubes are going to fit into 3 sided boxes with one side open on the bottom so you can slide the square tubing into the boxes. These boxes will be located where the tabs used to be. The clearence will be tight. When you slide the stage 2 cross bracing into these boxes the capped end of the tubing should be right against the back of the box. I drew I diagram of the box below. The open end of the box would be where the square tubing would be sticking out. Then to keep the tubing secure there will be bolts going through the box and the square tubing in 2 spots. So there will be 2 bolts for every box to spread stresses over a larger area.



Hopefully these pictures have given you guys a better idea of what I'm getting done although if not I dont blame you, the last time I had art was in 6th grade and my teacher (No lie) said I was artistically retarded.

I have the car now, he did measurements on Fri and I am bringin it back Mon morning to start fabrication. I'll keep you guys updated.

I really hope these things come out great (keeping fingers crossed)

P.S. I am going to be posting this in multiple forums as it concerns more than just 5th gens. So mods please be understanding about that.

 

Thats cool and all but are you making some for 3rd gens?

These are custom.. so technically any car in the area could get them custom made for their car.

If this guy ever created kits he would have to see quite a bit of interest and he would have to have a pretty solid template put together after fabricating them for several cars before he ever shipped a set out, if ever at all. This is just the first step. Lets see how my car comes out first

 

UPDATE on the SFCs. I did some research on the strength of round tubing VS square tubing and found that round tubing can be somewhat stronger while being lighter. So for the stage 1 bars that run the length of the cars I've decided I am going with round chromoly tubing, because of some of the things I read in this article from factory five racing.

http://www.factoryfive.com/table/ffr...ecs/frame.html

Mainly because round tubing had more tortional strength which the chassis and thus the stage 1 bars will experience some of. The square tubing is better for vertical strength. Thus they would be better for the center stage 2 section. And the box connection is very good. So there will be a combination of square and round tubing and the combination should be the best for weight saving strength and good connections on the bolts.

 

Why not just buy Warpspeed's? They have done all the R&D for you and charge a fair price. However, I suspect that you think it will be cheaper to just try and copy their design.

 

Only problem Warspeed is in the process of relocating to a bigger location and everything is pretty much in storage...I called last week and they said it would be another month or so before everthing is moved and unpacked....I think it would be worth it to wait for Warpseed they have done all the research and their product are quality that is just my 2cents....

 

Because warpspeed doesnt ever deliver. I'm not giving them my money just for them to never send me their erector set looking subframe connectors that are designed poorly and dont use chromoly

 

They are designed poorly? A few people have them on the 3rd Gens all satisified no?

 

most people found a large change when they installed stage 1, but saw little or no difference when bolting on stage 2.. If you have seen stage 2 than you can see why it probably doesnt add much performance. This is why I am keeping stage 1 the same except using higher quality tubing and only really changing stage 2.

Plus again... try getting SFCs from warpspeed... that company is a joke

 

What is SFC?

 

SFCs = Subframe Connectors

 

I haven't heard any complaints from the owner of the hardest driven car on this site, or any of the other guys who have them



Kind of strong words coming from someone who wants to build subframes out of square tubing....

Going out on a limb here, do you have WSP's SFCs on your car?

 

To be honest if warpspeed could even provide the product they say they carry I probably wouldent be going through with this at all.

Look I think warpspeed sucks. I was lied to many times before I got fed up and took matters into my own hands. If you dont agree with me ignore the thread and deal with warpspeed as you please, but I sure wont.

 

Atleast have the decency not to copy their design or slander it when your own is..... uhhhh..... see above.


As for service, the WarpSpeed lady > * in my experience
Then again I was ordering 3rd gen parts and seeing as that's how they started, maybe they just love us more

 

If they are in the process of moving, of course you will not be able to get parts.

I have a WSP Y-pipe, and SFC Stage 1 & 2. I have been nothing but satisfied with their service. I also have a WSP intake, but I got that second hand, sooooo.

 

I dont see how I am copying warpspeed. Warpspeed didnt invent Subframe Connectors and me using pictures of the warpspeed sfcs installed on cars to better convey to people what I'm planning to do doesnt meen I'm using their design. There are quite a few differences between this and the warpspeed design and I think thats obvious.


Seriously maybe they do because in both the 4th and 5th gen forums people have been responding much more postivly to my efforts to provide another option.

I think the 5th gen guys cant stand him because of threads like this. Among other things.

Post 15 was very tactfull on Dallas' part

And post 32 is part of the reason I'm doing this

 

:eek3: Wow, that was unbelievably ill advised on his part.

 

This thread says it all: http://forums.maxima.org/showthread.php?t=463656

 

Haha..DrKlop knows what I meen

 

I understand your frustration with WSP, but that's a lot of R&D for someone to create a SFC. Even if he's using someone elses design as a starting point to create his. How much are you expecting to pay for this SFC?

Once everything is said and done and your fabricator created the exact SFC you want, he has all the measurements and jigs needed to crank out another SFC without actually having a vehicle in front of him, what happens next? At that point do you ask for interested parties, will a price be sent at that point?
