I am thinking of getting the Modulo sports suspension from Japanparts.com. Any reviews on it. It says it only lowers 25mm which is 1". Which is what I like. I do know I will have to drill the front shocks mounting bolt bigger. It seems like the springs are aftermarket, and the shocks are made by Showa.

 

Well I've seen the Honda sport suspension kit (the same drop -2,5 cm) on japanparts.com but its white and springs are bigger than at your picture?
Why do jou think you would have to drill?

The modulo suspension is for the Jazz and they use 17mm bolts while we the USDM uses 19mm. I saw those too but I wish I could see a pic of it on a GD3.
