Welcome Marios. Care to share with us all the three items and we can help you determine legality (or muddy-up the grey area)?

Unfortunately, everyone has the right to post what they want. What is great is that you have the right to post a rebuttle and have the rest of the BB make up our own mind.

Of the 3 items listed:

Any 'shortening' to an axle is not permitted
Solid front motor mounts are not permitted (a front 'stayrod' may be ADDED, not substituted for a MM)
Batteries must be of the same size, type and voltage may be used - anything smaller is not permitted

As far as 'nice' guys? I think they are. This may seem a little extreme but you come off fine here. New driver with a car you bought from someone else...no issues. Heck, almost every car in the classifieds lists something questionable as a 'feature'.

If you think something is legal that someone else doesn't - debate it here - you will for sure learn all the angles!
