Sorry but i am a newby, i am getting ready to start a grabercar "la bala" chasis, however being a Nissan tech for 15 years I want to use a late '90 Sentra drivetrain instead of the Toyota the car was design for. I want to use as much of the front end as i can in the back, the sport spec racers, do it but i can not find a clear pic of the fabricated suspension arms, I look around here and some people has done it also, but the suspension pics do not show the parts needed to make it work, i would apreciate it if you guys can point me in the right direction. Thanks

Functionally it's certainly doable. Aesthetically though, the typical tall struts will stick out the top of most of the very low cars that people build here. I don't know if you're talking about struts or not, but because you're starting with an existing chassis design, it's designed around one particular upright. Using a different upright may potentially result in very different handling characteristics due to the pivot points being in different positions.

:lol: I was thinking of modifying the strut tubes to fit a bolt joint and just use a-arms, and about using parts on a chasis it was not design for it, that is why i came here. i think you guys are the experts at using parts in places there where not design for :oops:

I figured you planned to cut the tube done, that's fine. The problem is that the upper, lower, and steering points are different than what the designer designed the chassis around. "If" you can replicate the pivot points then you're golden, but otherwise it's a complete unknown what you'll end up with for handling. A first step would be to model it in the suspension calculator floating around here and see what the differences are. It might be fine, and it might not, but without checking it's random chance how it'll turn out.
