I made a comeback to the sport earlier this year and opted for the ZX-5 SP2 - there have been some 'interesting' driving moments from me so far as I find my feet again and this is what I have broken over the course of the year:
1 x front shock tower - trying to jump the big double at Cov and generally arsing around whilst doing it - definitely down to me that one -
1 x rear inboard camber link plate after landing on that corner's one wheel sideways over a jump.
and erm... that's it! I decided to rebuild the diffs after about 6 meetings and several long test sessions and swapped out the balls for ceramics in the process but that's it.
Mine is also built with the longer gearbox bolts (about 22mm M3 socket head cap screws - only couple of quid even at ebay prices), and the top shock mount bolts reversed which also speeds up changing the mounting positions so win/win really...
I was really very impressed by the quality of the kit during the build process, you know it's a quality product.
I initially thought it was quite a lot of outlay to begin with - maybe because last time I raced my dad bought me all the gear(!), but just because there are cheaper options out there it doesn't really make the Lazer 'expensive' - what's the B44 - £300? and the current FS2 is just under 350 at JE - about 3 full sets of tires difference in price which you'd go through without much of a second thought...
You're in the same boat as myself really Skye - having to spend out on everything at once (I haven't got around to getting a 2WD myself yet) is a bit eye watering and I'd be reluctant to buy a new kit so soon too, but if it's going to make the difference as to how much you enjoy the hobby maybe it's worth it? I'd wait and get the BB's in the kit though tbh or you'll find yourself itching to buy them anyway just like me
