Mick Doohan Posted June 15, 2009 Share Posted June 15, 2009 so you will have a 3mm gap in which to put a threaded sleeve lol. its getting fairly close but you may squeeze it in there. you will have to make up your own threaded sections and seats. bonus being you wont have to locate the spring at the bottom. as it cant go anywhere lol what's the thread pitch of those nuts ? 1.5 ?? ... if so you wont get to full thread depth before you break though .. and in this case .. id want at least 2mm of wall left you may get away with a 1mm base dimension .. so you would need 5mm overall to make it work .....just IMO Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted June 15, 2009 Share Posted June 15, 2009 nah closest km nut would be a km12 which is m55x2mm pitch. As I say, you will have to make your own platforms etc. Id say youd be better off getting soem 2.5" springs Quote Link to comment Share on other sites More sharing options...

Brock-Lee Posted June 15, 2009 Share Posted June 15, 2009 nah, the whole reason is to fit inside a 2.25"spring. so you go any bigger than 57mm and the spring wont fit over the threaded section. thats why I reccomend he go buy some 2.5" springs. gives you a fuckload more breathing room Quote Link to comment Share on other sites More sharing options...
Mick Doohan Posted June 15, 2009 Share Posted June 15, 2009 ok so spring dimensions are ID not OD ... my bad .. prolly half asleep if you all need the same size tube and want quantity .. once you have the tube set-up and can just part and thread .... it would take 4 pass's to cut the full form .. so lees than 5 mins to cut thread and part each tube ..... could be well worth pricing .. if you have the numbers Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted June 16, 2009 Share Posted June 16, 2009 i take it you guys arn't worried about the threads rusting over time? the threaded sections you buy at geogre stocks are cad plated, although some burns off when welding it on. I thought they had two options in length, one at about 100mm and the other longer, i always thought springs had to be captive when adjusted down for a cert so never bothered with longer versions just in case they undid themselves, but im probally wrong. cut and shorten the tubes with two bits of angle iron is how i normally do it i tryed threading up some tube on the lath then used some big nuts from steel and tube, but they were cast and the threads didnt hold, needed a finer pitch for more strength Quote Link to comment Share on other sites More sharing options...
Gaz Posted June 16, 2009 Author Share Posted June 16, 2009 Gaz, you can play with my springs after you give me back my brakes (no rush, I don't need them til October) Oh yeah had forgoten bout them, my car only came back from painters last weeked, its been in there since wedding cause I wasnt happy with the job they did.

My struts are 50.9mm O/D with paint on them. I am going to fit the 2.25 inch platforms. I ordered them today. Two 400mm weld on steel threaded tubes and the alloy lock nuts and platforms are a bit over $200. I bit of strut paint removal, a light hone of the threaded tube and 15 minutes in the oven should have the tubes on my struts I reckon. Pics later when I can be arsed Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted June 24, 2009 Share Posted June 24, 2009 Had a look at your struts the other night UJ ... very very lush! postage is required! Quote Link to comment Share on other sites More sharing options...
Gaz Posted June 24, 2009 Author Share Posted June 24, 2009 Yeap im going to 2.5 inch springs too. Going to use the 55mm KM nut and then make a bottom cup from a flat washer and a peice of 2.5inch exhaust tube. The exhaust tube will locate the spring up the centre. Then going to turn up some top hats which shouldnt be too hard, this will also fix my problem of my larger dia adjustable top plates as a spacer sleeve can be incorporated into the topcup easily. OR. what ya doing with ya 2.25" threaded tube of your existing struts UJ? Gaz Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted June 24, 2009 Share Posted June 24, 2009 Good new gaz the fulla im getting the adjustable pieces from just emailed saying there are two sets of 2.5" top hats so sorted Quote Link to comment Share on other sites More sharing options...
Unclejake Posted June 24, 2009 Share Posted June 24, 2009 OR. what ya doing with ya 2.25" threaded tube of your existing struts UJ?Gaz Do you mean my existing 2.5 inch tube and nuts? If so I imagine I could be persuaded to part ith them but I am not going to get a chance to do bugger all on the Cortina for another week or so.

Gaz Posted June 25, 2009 Author Share Posted June 25, 2009 Oh my thinking was wrong. Why ya getting a new full set if all you needed was springs? Gaz Quote Link to comment Share on other sites More sharing options...
Unclejake Posted June 25, 2009 Share Posted June 25, 2009 Oh my thinking was wrong. Why ya getting a new full set if all you needed was springs?Gaz I am changing from 2.5 inch diameter springs to 2.25 inch diameter springs so I need new platforms.I am making the change because I accidently ordered 2.25 inch springs and my new strut tops came to suit a 2.25 inch spring so the easiest option is to change the platforms to match the rest of the stuff. I bought new strut tops because my existing ones took up too much suspension travel. It suits me as I needed to move the 2.5 inch platforms on the struts anyway so there is no additional work, just an additional $200 Yeap im going to 2.5 inch springs too. So - don't you need 2.5 inch platforms?? You are confusing the fuck out of me. I will have a spare pair of 2.5 " threaded tubes, nuts, platforms and top caps in a week or two (and a pair of 400lbs springs to suit). I will probably put them on the market if you don't want them.

bubblegoose Posted June 25, 2009 Share Posted June 25, 2009 400lb springs in your car UJ ? does that even move ? im a bit of a newb at spring rates Quote Link to comment Share on other sites More sharing options...
Unclejake Posted June 25, 2009 Share Posted June 25, 2009 ^ I am upgrading to 450lbs. It does not move much but it is a dedicated race car so is unsuitable for the road Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted June 25, 2009 Share Posted June 25, 2009 whats the id of those tubes you have uj? Quote Link to comment Share on other sites More sharing options...
Unclejake Posted June 25, 2009 Share Posted June 25, 2009 Not certain until I remove them sorry, but I would guess around 52/3mm? Quote Link to comment Share on other sites More sharing options...
bubblegoose Posted June 25, 2009 Share Posted June 25, 2009 had a feeling it would be about that, too small for me cold be keen for the springs though, spare set for track abuse maybe Quote Link to comment Share on other sites More sharing options...
