Differences in IS-F years
I Just purchased a 2008 IS-F about 3 weeks ago and I want to know what are the big differences between 2008 and the rest of the newer IS-F? When I say differences, I mean like big differences and not like a color on the blinkers. I am new to this community and if anyone could possible give me a rundown it will all be appreciated.
Thanks in advance

Welcome! If you do a search there are a lot of topics related to this.
Biggest change came in 2010 w/ the addition of an LSD and updated infotainment system w/ USB & BT capability. New wheels in 2010 as well.
2011 + addition of LED headlights and instrument cluster change. 2011 + also had revised suspension.
2012 + different wheels and new interior color combos.
Those are the biggest changes.

Lexus dramatically changed the IS-F in 2011, here is Car and Driver's summary:
A Thorough Revamp
Still, the IS F had serious potential; its 416-hp V-8 left no doubt about that. But its ride and handling simply didn’t deliver. It would hobbyhorse down uneven pavement and batter occupants in a straight line but roll excessively in corners. For 2011, Lexus addressed these concerns in a big way, changing or retuning every major suspension component. There are softer front springs, stiffer rear springs, larger-diameter anti-roll bars front and rear, stiffer bushings on the rear subframe and rear anti-roll bar, and a new steering knuckle and front lower control arms for reduced unsprung mass. Oh, and the rear camber is tweaked as well. The honking V-8 and the eight-speed automatic carry over unchanged, but a Torsen limited-slip replaces the previously open differential. Engineers also retuned the electric power steering, injecting a dose of much-needed feel. With these changes, the IS F goes from subpar to front-runner.

Motor Trend reported similar changes in the 2011:
Although the powertrain and the car's 3800-lb curb weight remain the same, the suspension settings have been totally recalibrated. The combination of spring rate revisions and dampers, fitted with new high performance valves in addition to reinforced suspension member connectors and bushes, permit more front-end suspension stroke yet firm up the rear end. This generates greater traction and stability at high speeds. An unexpected byproduct of this revision is the car's more compliant ride, which Yaguchi says "was a bonus but something we aimed for." Adjustments to the steering power-assist mechanism made for more precise and accurate turn-in as well as greater feedback through the wheel. 2011 Lexus IS F Front The results are that the 2011 IS F can now be pushed even harder into corners; it stays more composed under heavy braking, at turn-in, and while experiencing changes of road camber and elevation. The IS F also exhibits less understeer and more rear wheel grip and stability. In fact, the rear end is now so tied down that a slight enhancement of front-end downforce might generate even greater all-round traction and stability. The new model laps the 2.8-mile Fuji Speedway in 2 minutes, 3.4 seconds -- nearly two seconds faster than its predecessor -- thanks to Yaguchi's subtle, yet substantial, modifications.

There's no question the later models have better suspension. The question unanswered is exactly what changed. Bushings? No indication. Aluminum housings for the hubs? Definitely not. Springs, shocks, and control arms in the rear? For sure. LSD? No doubt.
Worth it for the track driver? Undoubtedly true.
