To add spacers to your Timbren system you are correct when you said you need longer bolts. The kit you're referencing uses a M10 x 30 x 1.5 GR 8.8 bolt to mount to the frame. So you need a bolt that is the same thread pitch, and hardness, but longer, the same as the size spacer you want to use.

Since metric bolts use mm for length, there is a little bit of conversion. Roughly each inch will be 25mm. So for example, if you wanted a 1 inch spacer, you'll want to get a M10 x 55 x 1.5 GR 8.8 bolt.

M10 (diameter of Bolt in mm) x 30 ( length of bolt in mm) x 1.5 ( Thread pitch/ distance between each thread in mm)

I have attached the spacers from Timbren for you to check out.
