cutting is easy and don't weaken the arms
I don't think there will be another solution for you in the near future
see message earlier:

I cut the front suspensionarms with a rotating tool to sharpen scissors and so on
it's easy but you have to do it slowly, taking care not to take off to much material in the end
also scrap the same quantity on both sides and stay centered on all sides, with that arm to the tool
cut in front part where pin goes through, just 10 mm large to clear the towerplate to (see pix)

to fill the gap I bought some extra 4mm shimmclips, mine are from from xb8
I run white xb8 shocksprings to

result is spectacular , much more steering , like a jammin x1cr
car just twists around the curves, you have to ajust the rear though to get it more stable
I use a goldcoloured rear anti-rolbar and white xb8 springs al around
or you can play with harder front rollbarr, shocksprings or oil
