Underdog Posted June 8, 2015 Share Posted June 8, 2015 WT - for your future reference, the Spec.B has unique spring P/Ns and there are two different versions. One for the 5MT Spec.B and the other for the 6MT. I have found that the 6MT version will cause a 5MT car to ride high, especially up front, due to the weight difference between the trans and rear diff. Here is a list I put together: MY06 5MT Spec.B Front Spring: 20330AG720 Rear Spring: 20380AG540 MY07-09 6MT Spec.B Front Spring: 20330AG14A Rear Spring: 20380AG12A MY05-09 5MT GT Sedan (LTD & nonLTD) Front Spring: 20330AG02A Rear Spring: 20380AG01A MY05-09 5AT GT Sedan (LTD & nonLTD) Front Spring: 20330AG12A Rear Spring: 20380AG01A MY05-06 5MT GT Wagon (LTD & nonLTD) Front Spring: 20330AG02A Rear Spring: 20380AG05A MY05-06 5AT GT Wagon (LTD & nonLTD) Front Spring: 20330AG12A Rear Spring: 20380AG05A The Crimson Dynamo Link to comment Share on other sites More sharing options...
whitetiger Posted June 8, 2015 Share Posted June 8, 2015 It would be nice if we know what the specific spring rates are for each of the P/N's. I bet the differences are very small if at all. Link to comment Share on other sites More sharing options...
Underdog Posted June 8, 2015 Share Posted June 8, 2015 Yeah I have been thinking about getting a spring rate tester. The difference could be in the free length as well. The Crimson Dynamo Link to comment Share on other sites More sharing options...
whitetiger Posted June 8, 2015 Share Posted June 8, 2015 for spec.b versus LGT in the front, length is definitely different Link to comment Share on other sites More sharing options...
