Well - my car has 33 cm (rear) and 37 cm (front). BUT: yours must have bigger values, because all the missing parts (bonnets, doors, all windows, most of the interior trim) should have a weight of at least 200 ... 250 kg in total. I guess you should first assemble your car completely and then look wether ist's really too high.
