parts recomendations for weak link items

Since I am doing a bunch of work to my 2011 R3 that I recently bought, and cant confirm recent replacement on many things,I might as well address all the weak links.
Is there a parts recommendation for the following items that I would gain some peace of mind by replacing....

Ignition coils
fuel injectors
radiator
overflow tank

Anything else I should address while I am at it?

Thanks.

I think most of these are covered in the newbie threads/stickies but I'll play along

Ignition coils BHR OR SAKEBOMB
fuel injectors IF YOU'RE NA AND THEY ARE NOT LEAKING WHY BOTHER(FUEL PUMPS TEND TO GO FIRST)
radiator ANY NON EBAY ALUMINUM DOUBLEPASS OR BETTER RAD WILL WORK FINE (KOYO IS A PREFERRED)
overflow tank IF IT'S NOT LEAKING OR THE SENSOR ISN'T BAD WHY BOTHER

Anything else I should address while I am at it?
NORMAL USED CAR WEAR AND TEAR ITEMS, ALSO GIVE THE ENGINE MOUNTS A LOOK OVER

Thanks.

+1 Everything Sonic said.

~~More specifically, I have the CSF3164 radiator and have been very happy with it. The Koyo V2695 is nearly identical in price and performance. Can't go wrong with either.~~
Reading comprehension fail, my advice doesn't apply to an S2.

Fuel injectors should be fine. If you want to take it out and get it cleaned by an ultrasound machine then I guess go for it. I am not touching mine since there are no issues yet.

S2 stock radiator is also improved compared to the S1 unit. Mine is doing fine. Just make sure you flush it on time.

I put the Koyo HH radiator in my S2 and measured very little cooling performance improvement. I wouldn't bother with the radiator. The S2 radiator is fine. If you leave it alone and don't break off the overflow nipple, it should last ~20 years. If you do decide to replace the radiator, go ahead and do the hoses while you are in there. Just use quality rubber hoses. Don't waste your money nor aggravation on silicone.

I would focus my attention on the motor mounts. Mine failed last year at ~40K miles. I hollowed them out and filled them with urethane. Total cost: $40 and 1 week of cure time.

Thanks for the info Steve, I appreciate it.... Is changing the motor mounts a difficult job on this car? I have done it on some old cars - old camaro's and a truck, but nothing like this - thanks.
