Lowering the 87

[chevymotocross]

I'm in the process of gathering all the info I need before I order the components I need to lower my 87 shortbed. Here is what I came up with: DJM has the best prices. Only problem I found is with the DJM spindle. Since it's a 3'', it may cause my 15'' wheel to rub the lower control arm. I don't have factory rally wheels, I have 15'' alloy aftermarket wheels, unsure of brand. How much grinding is actually required? I don't mind grinding, but I don't want to grind excessive amounts away from the LCA and I'd like to avoid using a wheel spacer.

Unfortunately, if I can't use the 3'' spindle, I'm going to end up spending more money since I would have to use either a McGaughy's or Summit 2.5'' spindle and possibly a 1'' or 2'' spring to get the drop a DJM spindle would have given me, but I wouldn't have to worry about grinding. Plus, now, I'm spending more, since I'm not buying one complete kit, now I'd have to buy the flip kit seperate, since I'm not getting it all from DJM if this were to happen.

Are pinion shims required? I'm doing a flip kit. Haven't heard much about these but I wasn't sure if they are required?

Does anyone know, if DJM's complete kits come with the shock extenders? I'm guessing I have to purchase them seperately.

I was planning on just the 3/5 DJM drop or close to it (if I had to go with the 2.5 spindle and 1'' or 2'' spring as I stated above), but DJM also offers, for not much more a 5/5 drop which includes an additional 2'' lowering spring. Will this rub 255/70/15 tires? I think for now I will just go with a 3/5 drop and add drop springs later if I want more front drop, but I was just curious. I'm hoping 255/70/15 tires won't rub on a 3/5.
