You might get an idea of whether you'd like to tackle it yourself from the following article: Lowering Spring Install - ArticlesHow much should I expect to pay for installation for lowering springs on 987 Boxster S with out PASM? Any DIY instructions?
Yes, just to clarify, the $600 I paid was just for the service. I bought the springs separately on eBay for around $210.Ita a real tedious and technical DIY and like interpol said you need a professional allignment before driving so IMO its best to seek out a good shop to do this . I had H&Rs installed a couple years back and have had NO issues . I am really happy with the results all around .
I have seen the cost of this mod anywhere from what interplo posted $600.00all the way to $1,500 I paid $725.00 including the allignment and springs ,Interpol got a smoking deal if that includes allignment .I think $700.00 to 800.00 including springs and allignment is a great price if you can find it
