I recently purchased some koni str t and am looking to either get the tein s tech ska22 (everywhere I look tells me a different spring rate for some reason)or megan springs spring rates of 280F and 230R...I know the koni str t cant handle high spring rates and aren't recommended to drop car under 1.5" so I am staying within that range....Looking for opinions on which of these two springs to choose....also I plan on doing this work myself and have never attempted it so can anyone tell me if there are any other parts I will need to do this job? like mounts or anything of any sorts? I have no Idea how the strut and springs go together as far as what I might have to use off the old struts and what is recommended to just replace...I plan on using youtube for instructions on how to do the job..with youtube and forums like this I can do just about anything lol...thanks for any help or advice in advance..

 

well according to tein website they are 157 front and 291 rear..why are all other springs more in front an less in rear but these are opposite?

 

the tein's you are looking at might be running a spring setup the same as a ep3. hence the high rear spring rate
