Rear GTR shocks on the front

I did the rear shock tower mod on the front as detailed by others, and put full rear GTR shocks (0 limiters) on.  The main issue with the rear shock tower is that it’s 17mm wider than the front shock tower, which means your shocks are mounted out way too far, especially when considering the taller mount.  Extrapolating from the stock shock positions, with the taller tower you would want to mount the shocks even more inward on the tower!

Most RC cars have the front shocks laid down flatter in the front than the rear.  Going to a rear shock tower makes that more difficult.  To combat this, I mounted the top shocks all the way inward, and the arm mounts all the way out.  It’s still too vertical for my liking, but that’s the best I can do at this point.

This also got my droop about where I wanted it front and rear.  At full extension, my wheels are about the same front and rear, with the front slightly higher (6mm) than the rear.  I don’t recall the stock droop on the front, but it was something like 14mm shorter than the rear, which is a massive difference.  I now have 42mm of shock travel at full extension, which should soak up the jumps much better than before.

And the one thing I don’t see people talk about when mounting long shocks on the front is the compression distance on the front arms.  Thisis why you pretty much have to use a taller shock tower on the front when using longer shocks.  You need the wheel to be able to compress past the bottom of the chassis so that you have some additional room when landing cockeyed on a front wheel.

Even with the chassis bottomed out, the front wheels still have room to give.  You need this, else your shocks will get slammed when landing off-center a little bit.
