slpadmin Posted June 1, 2009 Share Posted June 1, 2009 Hello Z Enthusiasts, This is actually my first post, so be nice. I've owned two 240z so far and I absolutly love them. I have a lot of passion for the car. I restored my 73 240 and then sold it (didn't want to but I wanted an older one that I can really have fun with). The 71 Z has stock front suspension and let me tell you, it's horrible. I've been in the market for a coilover/spring upgrade. I'm afraid I might bend my frame over time and ruin my Z with the road conditions (I live in Sacramento, California, yeah worst roads in the U.S.). When I'm driving I hear the front springs hit the strut tower stopper (LOUD) and I know it's not a good thing. So, to the point, I know there’s Arizona Z Car.com and others sites that sell the kit, but I found this kit on Ebay and wanted some feedback. It looks like a quality set but the price doesn't match up with the quality. So, I hope I can make the right decision in suspension with your help. Any guidance is much appreciated. I'm running a ZZ4HO 4 bolt main block at about 550+hp with a t56 6 speed manual transmission. So the front end is heavy. I raised it on the rack and I can see that both springs in the front are completely compressed. So I know I need a kit bad, maybe a 250 lbs/in spring set all around. Thank you and heres the link to the kit on Ebay: http://cgi.ebay.com/ebaymotors/Racing-Dual-Coil-overs-Coilovers-DATSUN-240Z-70-74-NEW_W0QQitemZ330334187247QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item4ce973aeef&_trksid=p4506.c0.m245&_trkparms=72%3A1171%7C65%3A12%7C39%3A1%7C240%3A1318 Also, I've attached some pictures of my Baby, 71 Z.

garvice Posted June 1, 2009 Share Posted June 1, 2009 Nice car mate. The add doesn't actually say the quantity that the price includes. It keeps using plural, so I assume it is for at least 1 pair, but you might want to ask if you think it includes all four. I can't comment on the quality, but I have seen similar priced sleeves (Look the same) in aus for a single pair. You do know that you will still need to section and weld these to your struts plus provide shocks right? Quote Link to comment Share on other sites More sharing options...

johnc Posted June 1, 2009 Share Posted June 1, 2009 You really need to read the stickies in the Suspension forums and the Strut FAQ. All your questions will be answered there. Quote Link to comment Share on other sites More sharing options...
slpadmin Posted June 2, 2009 Author Share Posted June 2, 2009 I've read through the stickies and a majority of the information is based on someone’s decision to go with a certain style. The reason I posted this thread was to see if someone by chance that converted their Z and put a big block, like I did, might possibly provide what setup they used to hold up the weight. I don't want to make a decision to use, "x coilover set" because John Doe did, he might have been running an original L24 engine. See my point? What year make a model car do you have John? Did you convert your cars engine? What type of coil over system are you using? Adam Quote Link to comment Share on other sites More sharing options...
johnc Posted June 2, 2009 Share Posted June 2, 2009 If you're looking for an example to follow, then you need to search and find some of the members that are running BBs in their 240Zs. If you want to understand what the logic is behind the selection of spring rates, which would help you make your own decision, then keep reading in the Suspension topic.

Drax240z Posted June 2, 2009 Share Posted June 2, 2009 What year make a model car do you have John? Did you convert your cars engine? What type of coil over system are you using? If you are looking for the exact replica of your setup, so that you can copy a particular package it's going to be tough going. Best bet is to follow Johnc's advice, learn about the options and make an informed decision. Each car is different, but you'll probably be able to get a good general direction through other members trials and tribulations posted here. FWIW, I don't think you want to copy Johnc's setup for the street... Quote Link to comment Share on other sites More sharing options...
