GT3 versus GT3 RS

[Left Hander]

I have heard the RS has a fully adjustable suspension and in the end will save you $$ - i.e. the money saved not buying the RS will be spent on susension upgrades, etc to get the non-RS to where the RS started. Reading the specs on-line it says the non-RS has adjustable sways, 6 possible degrees of camber... I have heard the RS has a light weight flywheel, is 50 pounds lighter, a tad wider.

(I searched the forum for this and did not find it, apologies if this is a duplicate post and I missed it ) So interested in knowing what is different between the two models. Figure those who own them are the best source. I am interested in a great track car set up.

thanks!
