Guest FLZ_Boy Posted August 8, 2013 Share Posted August 8, 2013 I'm researching JDM Supras OEM spring color codes. Are the front spring color code dots both the same? In particular, do the factory Bilstein use the same color dot code for the front driver and passenger spring? Quote Link to comment Share on other sites More sharing options...
Guigsy Posted August 8, 2013 Share Posted August 8, 2013 Why. Does the colour of the spring give you more hp? Quote Link to comment Share on other sites More sharing options...
Guest FLZ_Boy Posted August 8, 2013 Share Posted August 8, 2013 It determines proper stock ride height of the Supra. USDM Supras have different color codes to determine if the front spring belongs on the driver side or passenger. I received a 96 SZR complete suspension (Bilstein and Springs)I notice the front springs had the same color code. I'm curious now if JDM Supras needed different springs. Right now my USDM Supra has uneven ride height with the 96 SZR suspension. I figured JDM Supras didn't have different color code springs since the driver weight would balance out the ride height. Whereas, the USDM driver side would only compound the ride height on the driver side to be even lower. Quote Link to comment Share on other sites More sharing options...
Nic Posted August 8, 2013 Share Posted August 8, 2013 Just had a look at the EPC, the US spec Supra has a different part number for the left and right front springs, the rears are the same part number each side. The J-spec and UK spec Supra use the same spring part number left and right. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 9, 2013 Share Posted August 9, 2013 This is because the average American driver is obese, is it not? Quote Link to comment Share on other sites More sharing options...
Guest FLZ_Boy Posted August 9, 2013 Share Posted August 9, 2013 I'm glad Toyota thought way in advance back in the 90's that the average American would become obese by the turn of the century. However, irregardless of driver weight, now I just need to swap out the passenger side to the USDM passenger side spring to bring her back to the correct ride height for a LHD.

marc_p Posted August 9, 2013 Share Posted August 9, 2013 I'm glad Toyota thought way in advance back in the 90's that the average American would become obese by the turn of the century. Well don't us owners always say that Toyota seriously over engineered the car so we can still be competitive 20 years later Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 9, 2013 Share Posted August 9, 2013 The spring rate variation, side to side, is so small I doubt you'll see any visual difference in ride height by using the biased spring rates, left and right front. We are talking maybe a 2% change in spring rate, or maybe a 4% change in unloaded spring length. Quote Link to comment Share on other sites More sharing options...
Guest FLZ_Boy Posted August 9, 2013 Share Posted August 9, 2013 Actually, there is a good finger difference in the gap between the driver and passenger side. As for spring rate difference, you are correct the variance is small. Quote Link to comment Share on other sites More sharing options...
