pjo046 Posted September 2, 2005 Share Posted September 2, 2005 Well, I have sent in my application for the rebuild of my car. Here in Norway, the vehicle authorities are very strict, and one has to get aproval to for example make an engine swap. Since I am wanting to swap the L24 for an L28ET, I also have to document that I at the same time upgrade the suspension and the brakes. I have chosen the coil overs from modern motorsports. Now the problem is, that for the springs to be approved by the authorities, they have to be cleared/accepted by an independent, aproved lab. For example TÃœV approval or DOT approval. I don't think the hypercoil springs I have have some sort of approval like that. Does anyone know of some documents on these springs that I can use? Maybe some of you who are selling these springs? I just need some documentation from a testing lab, that states how big a load they can handle, etc etc. I have 10" long springs front and rear with 2.5" inner diameter. The front springs are 175 rate and the rear ones are 200 rate. PLEASE HELP ME OUT HERE THOSE OF YOU WHO CAN!!!!!!!!!!!! If I don't find a solution to this, I'll never get the car registered and get plates on it. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 2, 2005 Share Posted September 2, 2005 Have you tried contacting the spring manuafacturer? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 2, 2005 Share Posted September 2, 2005 There has to be a TUV approved 2.5" spring available locally. H&R or some other European manufacturer should be able to help you. Quote Link to comment Share on other sites More sharing options...
pjo046 Posted September 2, 2005 Author Share Posted September 2, 2005 Yes, I contacted Hyperco, the manufacturer of hypercoil springs. They couldn't help me. They said the springs were primarely meant for racing, and they didn't endorse using it for street-legal vehicles.... Not much help there.... Not sure who else to contact. I have heard that no coilovers are TÃœV approved..... If so, I am in deep trouble.... Also, I don't know if the TÃœV approval has to be vehicle specific..........

pjo046 Posted September 3, 2005 Author Share Posted September 3, 2005 If anyone can get me the necessary documentation for the spring-type I have, I'll pay that person 30$! No question about it!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
260DET Posted September 3, 2005 Share Posted September 3, 2005 There is another way, use the stock suspension to get it approved. Then................ With me? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 3, 2005 Share Posted September 3, 2005 There is another way, use the stock suspension to get it approved. Then................ With me? In his first post he says that he has to document the upgrade to brakes and suspension for the extra HP engine Quote Link to comment Share on other sites More sharing options...
pjo046 Posted September 3, 2005 Author Share Posted September 3, 2005 That's right. And I have also mentioned in my application that I am wanting to use coilovers. So they will probably look at that area specific when checking the car. Also, my strut-housings are already modified, så I can't use the stock springs on them anymore....
