I already have Alston SFC's on my car, and I have a set of Spohns laying around that I'm not sure if I need to use. I will be dropping in a 400 that's been professionally built by a machine shop and estimated to produce about 500 hp, and I don't know how much torque. If the Alstons will be enough to keep my car from destroying itself, I can be perfectly happy. I'm wanting to know, however, if they will be enough to handle the power of an engine like this, or if I should add the Spohns as a backup.

Thanks,
Eric

 

requires alot needed strength in the chassis. You could prob put the spohns and alstons in together....not sure though... i know you can get sfcs from UMI that will take that torque....heard from the company itself that they are cable of taking the torque of a 700+ horsepower motor without any problems.

 

It's perfectly possible to fit both Spohn and Alston SFC's to the same car - as you know they connect to different areas. If you already own a set of Spohns, then as far as I'm concerned it's a no-brainer - go ahead and fit them.

That is unless you have problems with exhaust routing, but that's more likely with your Alstons, than the Spohns.

I have pics of them both installed on my own GTA and keep meaning to shrink the pics and start a thread on it. I'll try to post a link to thread in this one if I do it in the near future.

Remember Eric, you don't NEED to use them, but it will not do any harm. The disadvantage of extra weight is insignificant in comparison to the added structural rigidity.

 

I know they will fit, and I'm not concerned about the weight. This is actually kind of bad, but I can do a lot of things, but I don't know how to weld. I would have to find a shop around here that I trust to weld them on, and then I'd probably have to pay $150 - $200 to have it done, and I'm just trying to decide if it's worth it. I would also like having them if for no other reason that to use them as jacking rails. I'm leaning more towards keeping them, so thanks for the opinions.

I think it only cost me about $50 to get mine welded.
