GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 I have to get the back end up asap. I have the KYB's. I have the varyable rear springs from QA1 I need the collers and nut, and a mount. Can I just rock the stock upper mounts? Can I just rock new upper mounts? What was the final coller and nut that we all found to be best? I dont want to hone it out. Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 These are the parts you want... http://shop.a1racing.com/cok12452-h.aspx http://shop.a1racing.com/cok12460.aspx ES Isolators PN 9.6103 2.5" ID by 12" long coilover springs. I used QA1 300lb springs.. http://www.summitracing.com/search/brand/QA1-Precision-Products/Department/Chassis-Suspension/Part-Type/Coil-Over-Springs/Inside-Diameter-in/2-500-in/Length-in/12-000-in/?Ns=Rank|Asc Quote

Here is the progressive rate spring QA1 has http://www.summitracing.com/search/brand/QA1-Precision-Products/Department/Chassis-Suspension/Part-Type/Coil-Over-Springs/Inside-Diameter-in/2-500-in/Length-in/12-000-in/Progressive-Rate-Spring/Yes/?Ns=Rank|Asc The coilover sleeve I listed DOES NOT need to be honed out on KYBs.. I found out by trial and error with other sleeves.. The ones I posted are good to go!! You can use stock mounts, my thread shows exactly what to do.. They work fine. I thought they were making noise over hard hard bumps, but it turns out it was my mufflers hitting my trunk! I would get new stock mounts... Odds are the ones you are taking off are junk.. Just get the cheapest stock ones around. It wont be too much longer until I get to buying a set of the custom mounts I designed that Mark will be having made.. I can then test them and get back with more feedback Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 I have the QA1 springs and ES Isolators. I just need the sleeves. I have read that 5 inchers are best? Your rocking the stock mounts. do you drive it? how many miles on them so far? any problems? Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 how many nuts are required? Most coil overs require 2 per a strut? Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 I have the QA1 springs and ES Isolators. I just need the sleeves. I have read that 5 inchers are best? Your rocking the stock mounts. do you drive it? how many miles on them so far? any problems? 5" is plenty.. It gives more than enough adjustment... The 7" other people have used is NOT neccessary unless they want to lift it like a monster truck.. Ive had them on for over 6 months now or more I think... Ive put about 13000 miles on them.. No issues at all really. I would highly recommend having a strut tower brace though. I never tried them without as I didnt want to put undue stress on the towers.. Although our towers are quite strong enough to take the load of the car with coilovers without issue. Just a strut tower brace is guarenteed reinforcement.. I though I was getting a weird noise, almost like the mount was poppign with a hard thunk over hard bumps or big potholes, but after having my full exhaust redone, it went away!! Turns out my right muffler was banging my trunk well.. Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 how many nuts are required? Most coil overs require 2 per a strut? Only 1 nut per strut... Hey, that rhymes It has a setscrew to keep it put (antiseize the hell outta everything!!!) I found out the hardway when it galled and stripped. I had to drill it out, and put in a much larger bolt for a set screw.. Which actually works out easier now.. The reason we only need one of these nuts as they are much much much thicker than the 2 thin ones that other coilovers use, espeically the cheap ricer ones.. The 1 we use is much more stable as the lower spring seat as the cheap 2 thin nuts.. Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 Do you have any pictures? Umm, in my coilover thread there are tons of pics.. Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 I read your tread like a month ago....... now i cant find it......where is it?? Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 I read your tread like a month ago....... now i cant find it......where is it?? I dunno, I just tried looking for it too Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 ok I am not wierd I found it!!!! http://www.w-body.com/forum/index.php?topic=71448.0 Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 what is the bearings for in this picture? Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 Those bearings are for the fronts I put together... Im just waiting on getting the front mounts I designed as well off Mark... Well, gotta send him the money so he can get a set made.. I designed mounts for front and rear.. Those cone shaped upper spring seats, ignore them. They were gonna be used in an original idea, but due to the strut rod diameter and load ratings, I couldnt go with the idea I originally wanted.. Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 what about instead of using a es bushing or using it and what is in this picture? Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 The bushing will help shut down some noise that may happen with the spring bare to a metal surface. While its bare at the bottom of the spring, there might be a greater chance of noise happening if you have both sides resting on bare metal.. Plus, nobody makes those upper seats pictured in the TDC setup... Just easier to use the ES Isolators (they are cheap) and stock mounts until the proper custom ones can be purchased.. Quote
kuntzie Posted June 11, 2009 Report Posted June 11, 2009 im running the same parts except the springs im using are 500s or 550s as i didnt want any movement back there. Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 im running the same parts except the springs im using are 500s or 550s as i didnt want any movement back there. Drag racing im assuming??? Only reason you would want springs that stiff on our cars.. I didn spring rate calculations, even at hardcore roadracing you would only want a 425lb spring max... 300lb are good for a daily driver, whereas the variable rate ones I posted would be even better actually. Just when I needed springs the variables werent available.. And if you want to go with the best spring out there, get Hyperco springs.. They cost about $70each but are the best out there for quality, spring rates being much more accurate, and keeping the rate as advertised over the life of the spring.. Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 I can purchase the proper ones right now......I just need them tooooo fast and I cant be the tester. I dont drive enough to test them, plus I am not taking out the stereo a bunch of times. Quote
GP4U2NV Posted June 11, 2009 Author Report Posted June 11, 2009 these are the ones that I am installing http://www.jegs.com/i/QA1/122/12-175%252F350/10002/-1 175/305 varable rate. Quote
BXX Posted June 11, 2009 Report Posted June 11, 2009 these are the ones that I am installing http://www.jegs.com/i/QA1/122/12-175%252F350/10002/-1 175/305 varable rate. Those should work great!! They were the ones I was thinking of getting, but I wanted to wait until I tear everything back apart when I do the custom mounts,, Since I designed them, I should actually be the tester, plus I drive a lot on the highway and in town on rough roads..
