Default Difference in susp,setup from slicks to DRs

Im switching from slicks to 275 DRs. only had the car out for a few passes on a totally new combo( went from N20 to turbo) but had slicks. 60d 1.30s which i thought wasn't too bad for a new combo,driver learning a new starting line technic,you know..all new ball game..
so now I'm going with DRs and was wondering what changes i might need for the switch.
right now my setup is

rear Strange Coil overs (single adjust) w/130lb springs.solid hiem joint U/L C/As ,anti roll bar

front Hal single adjustable struts 150lb-14in springs all tube front susp.

besides maybe changing a few parts..does a DR like higher/lower C/G
shorter or longer C/G

tighter or looser front strut setting?

I'm sure not many people making these radials work will share EVERYTHING,but a little help would be appreciated . Thanks

I will start that virtually every fast shop and tuner/racer swears you must have double adjustable shocks for the rear and it is a very good idea on the front end too.

With 100 % it may need to be a little higher and the shocks need a tighter comp most of the time. It will also show any issues with front ends smoothness of travel. Just think of it being a much smaller window to tune in.

OK ,thanks for the replies.
i plan on getting new rear shocks.double adjustable.ill just sell my old single adjustables.
i do have some adjustments on the rear control arms,so i can add a little more AS. does it matter if i get more AS if the connecting points are shorter? i'm guessing i have no choice on that.should the CG be moved up or down or try to keep it the same by moving both the upper and lower C/A or just one ?

I know I have no monster of a car,but when I tightened my strange single adj. Up front it helped the car launch with the more power I was putting down. I think before it was coming up and back down too quick and taking weight off the rear tires. My 2 cents.
