SOHC Posted October 15, 2014 Share Posted October 15, 2014 This is something I know nothing about, I kinda slapped this car together from anything I had on hand, it has some kind of coil shocks off a T bucket. This is how it sat with the body off With the weight on those half shafts should be nearly leave with the road, I have the preload wound right up but its not enough, there is too much sag, springs not havy enough. Can any one ID those shocks? are they a std thing I can buy heaver springs for? Quote Link to comment Share on other sites More sharing options...
Rookie Posted October 15, 2014 Share Posted October 15, 2014 Haha, the reason is because you only have half of the shocks attached. They look like stock jag items. It is supposed to look like this: 1 Quote Link to comment Share on other sites More sharing options...
Testament Posted October 15, 2014 Share Posted October 15, 2014 that single shear mounting to the arm is pretty yuck too also swingaxle? or does the halfshaft act as some kind of top arm somehow? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted October 15, 2014 Share Posted October 15, 2014 Pretty sure the axle is the top arm. Aren't early corvettes the same? Quote Link to comment Share on other sites More sharing options...
SOHC Posted October 15, 2014 Author Share Posted October 15, 2014 The cert guy sed he wouldn't pass the cert If I used 4 shocks, it has 2 universals in each arm. Quote Link to comment Share on other sites More sharing options...

It has control arms/ radius rods and some stays witch have been put on since this pic Quote Link to comment Share on other sites More sharing options...

He sed on such a light car 4 shocks would be overkill and suspension wouldn't move. I am thinking it I just put the jag springs onto my dampers might work?

SOHC Posted October 15, 2014 Author Share Posted October 15, 2014 A few t buckets just use 2 shocks. Quote Link to comment Share on other sites More sharing options...
Rookie Posted October 16, 2014 Share Posted October 16, 2014 Na the only way to get this right will be to match spring rate to desired wheel rate. A jag isn't that heavy and most of the weight is up the front so you will probably find that if you use jag springs they will be too soft/ what you are probably using already. 2 Quote Link to comment Share on other sites More sharing options...
SOHC Posted October 16, 2014 Author Share Posted October 16, 2014 I am not too fussed as long as its not saggy like it is now. The springs are about 10" long and 3" ID, if anyone had or knows of something that would work? Quote Link to comment Share on other sites More sharing options...
mikuni Posted October 16, 2014 Share Posted October 16, 2014 Maybe some Honda springs, but ironically it would probably be cheaper to just buy a 2nd hand set of coilover springs on TM 1 Quote Link to comment Share on other sites More sharing options...

Testament Posted October 16, 2014 Share Posted October 16, 2014 Brand new ones are not expensive either really 1 Quote Link to comment Share on other sites More sharing options...
Nominal Posted October 16, 2014 Share Posted October 16, 2014 You can do some maths if you know/guess the corner weights e.g. http://www.ridetech.com/info/spring-rate-calculator/ 1 Quote Link to comment Share on other sites More sharing options...
SOHC Posted October 18, 2014 Author Share Posted October 18, 2014 I have no way of weighing anything, I will just try what ever I can find. Quote Link to comment Share on other sites More sharing options...

Mk1Daniel Posted October 18, 2014 Share Posted October 18, 2014 Archers springs in rotorua make custom springs to suit given specs I think?? Quote Link to comment Share on other sites More sharing options...
SOHC Posted October 18, 2014 Author Share Posted October 18, 2014 I need some heavy duty scales or something to weigh the back of the car or something? or should I ask for some springs twice the strength of what I have? I don't know where to start. Quote Link to comment Share on other sites More sharing options...

I don't know where to start. quiz someone who has similar set-up to get spring rate. i know there's plenty of variables, but anyone using that rear end will utilise very similar mounting points and will have a similar loading on it. once you have an idea on the spring, either hunt for used ones or go to a speedway supply, as they are usually a lot cheaper than performance/ricer suply. 1 Quote Link to comment Share on other sites More sharing options...
