for those who do not care for "nuts and bolts" types of SCALE chassis, do a little research and see what is being built and raced n Europe. REAL SCALE Model Car Racing- detailed to perfection, chassis that perform very well, cars handle great, but are NOT in any way to be compared to wing cars, in either speed, handling, or looks.
I still don't understand these types of discussions that compare apples to oranges. And the other complaints about rtr cars needing tuning once removed from the box- then tell me why racers go to extremes to rewind motors, balance motor parts, adjust brushes, chassis tweaks, etc etc etc??? Or, let's open up the scratch building comparison discussion, opening up another "can of worms". Just watch the amount of soldering and other types of work done on slot cars at any commercial race. Do your Parma, JK, etc cars work perfectly "out of the box"??
The answer here is simple: race BRM cars by themselves as it's own class- they are fun and a challenge to race; race Scaleauto cars as it's own class- they perfrom great out of the box, just add their own foam rubber rears for commercial tracks with light spray (or no) glue. I did this for many years and it was amongst the most enjoyable racing i have ever done. And yes i also build, tune and race H&R Racing hardbody cars with model kit bodies- again, race them in their own class. There ya go fellas: 3 separate SCALE Model Car Racing hardbody 1/24 scale classes that perfrom well on a good road course track. and btw- a box stock Scaleauto Porsche, with foam rubber rears, can match or beat any super tuned H&R hardbody car I have raced against.
Back to the original topic- these new BRM Trans-Am cars are beautiful, I have only minor issues with them- not much braking, but have yet to mount foam rubber rears to them or try either a different motor or gear ratio- But these are all standard tuning options for any model or scale or type of slot car, based on the track you are racing on. As far as complaints about too many crashes with BRM cars and body damage- I have raced al of the above mentioned hardbody cars, with 2 types of racers: one type can't keep their cars in the slot and crash often, others barely ever come out at all. With the first group, body damage was a big issue. With the second group, body damage was not an issue.
If you race these types of hardbody cars beyond their capabilities, then body damage will occur. So I do not really see any of the complaints brought up about these cars as significant issues.
