cyrus Posted May 7, 2003 Share Posted May 7, 2003 I will narrow it, redrill the 6 lug pattern and do what ever it take to shove the suspension in my LS1 powered z. It WILL not break anymore!!!hahahahah!! Has anyone done this?? Cyrus Quote Link to comment Share on other sites More sharing options...
S30Z Bushido Posted May 7, 2003 Share Posted May 7, 2003 sounds like a pretty cool project. make sure you take lots of pictures! what is the gear ratio in a viper's diff? Quote Link to comment Share on other sites More sharing options...
Mudge Posted May 7, 2003 Share Posted May 7, 2003 Do they have an aluminum rear? Quote Link to comment Share on other sites More sharing options...
cyrus Posted May 7, 2003 Author Share Posted May 7, 2003 aluminum=yes 3.07 ratio Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted May 7, 2003 Share Posted May 7, 2003 I believe it is also a DANA36 like the C4 Vette. That is a wide car and you will need to do a lot of widening unless you are using wide flares. Quote Link to comment Share on other sites More sharing options...
cyrus Posted May 8, 2003 Author Share Posted May 8, 2003 No it is a dana 44 and it is different than the corvette dana 44. Remember that do not break with 500 ft/lbs of torque and 460 hp on 345/25/18's in a 3350lb car. I hope it will hold with my LS1 and slicks. Wheelies here I come! Scottie the suspension does not tie to the differential, so I can mount the suspension anywhere I want. Then shorten the axles to fit. This may be too easy. The real problem is the viper is 6 lug on 4.5 inch. I may have to go to the furd bolt pattern. The holes alway are in the way for a redrill.

johnc Posted May 8, 2003 Share Posted May 8, 2003 Remember that do not break with 500 ft/lbs of torque and 460 hp on 345/25/18's in a 3350lb car. Yes they do. I can put my hands on at least a dozen broken Viper rears done with stock motors making less horsepower and torque then you list above. Heat is their big problem. When you got the rear suspension did you note the angles of the upper and lower control arm inner mounts? Those angles (in both planes) are critical to getting the correct caster and anti-dive and you'll have to duplicate that or you'll end up with some really weird geometry. Good luck and call Erik Messley at (714) 713-9096. He knows the Viper and the Z better then most anyone out there. Quote Link to comment Share on other sites More sharing options...
Guest livewire23 Posted May 10, 2003 Share Posted May 10, 2003 while we're on the topic, anyone know of some good IRS's that are a bit narrower than the vette or viper? I'm thinking about swapping the whole IRS out of my car, (just a thought), but I dont want to hack up the halfshafts. Would a 280ZX rear suspension setup fit into a 280Z bolt-in? I want something with replaceable struts so i dont have to cut and weld when i go coilover. Quote Link to comment Share on other sites More sharing options...
j260z Posted May 10, 2003 Share Posted May 10, 2003 livewire23, go to http://www.modern-motorsports.com Ross C will set you up with a set of coilovers that do not require sectioning. Quote Link to comment Share on other sites More sharing options...
Guest livewire23 Posted May 10, 2003 Share Posted May 10, 2003 you still have to grind off the current struts though right? That's alright, I finally dropped the entire transverse link and I'm done hating it for now. Quote Link to comment Share on other sites More sharing options...
j260z Posted May 10, 2003 Share Posted May 10, 2003 yeah. all you have to do is grind off the spring perch and then weld on the new perch that comes with the kit. Quote Link to comment Share on other sites More sharing options...
