No, definitely not. They will be worth more in credits than the extra SP you will earn from them.
I want to say that you are doing a great job with the whole bundle breakdown and all but this time you are wrong - yes spare parts to credits in fact have the best conversion rate BUT if you use your spare parts and buy 30 days of premium time you will get way more credits than you would if you convert spare parts to credits.
