do not know to much about my 95 trans am, but i have been told that i need to throw away my optispark and go with coil packs how do i do that?
Like so..
Seriously though as long as the OPTI is maintained well it performs. Get it wet then you have problems. There are kits out there, it depends on how much you want to spend.
I agree with ss.slp.ls1. the origional stuff is fine, but the rumors to less informed people believe that the OPTI is complete junk. You can go to a Delteq system also if your wanting individual coil packs, but as stated above the Delteq uses the origional OPTI to operate. If the car is basically stock then there is no need to worry about it until it gives you problems and if it does just put a new OPTI in it and it will give you many miles of trouble free service.

Delteq isn't technically a indivudual coil per cylinder ignition system. It uses one coil for a pair of cylinders. And as you stated, it still needs a functioning opti for it to work properly, so it effectively would eliminate cap & rotor failure, which is the usual problem when an opti goes bad. But if you thread lock the rotor screws of your opti, you won't have that problem. The Delteq system isn't bad, just unnecessary IMO. And with more components to troubleshoot when problems occur and virtually zero customer support, I would never buy a Delteq. I have even removed a couple systems off of friends cars and returned them back to stock.

was your car originally a 6 speed or did you swap rears? the A4's have 3:23s if they have the performance GU5 axle and 2:73s if they have the standard axle. only the 6 speeds had 3:42s

How about just changing the cap and rotor on the opti like you would on any other distributor after 75-100,000 miles. They need maintenance and love too. GOT 120,000 miles out of one opti and 247,000 miles on the other vehicle and its on its 3rd cap and rotor, 1st 2 gm , 3rd now msd (Vented).
My third lt1/4 vehicle has an ltcc/dynaspark and only has 10,000 miles on it since the upgrade/build, I like it, but has way more wires and cost a lot more to do. I have not put the miles on it, as it's my toy and gets driven on nice weekends only, so I can't say if it's a great deal more reliable than the other opti cars or not, but it should be
Imho If you dead set on a coil pack setup go LTCC and Dynaspark gen 3
I have not seen, nor can I give you any experiences on this kit, but you can also look at the LS conv kit made by EFI connection, http://www.eficonnection.com, but that is by far from cheap if you get all of it from them, (wiring harness) but they have info to help cut some of the cost down by doing the labor on the wiring harness yourself.
Also there was another guy (akafred), I think that was doing something like EFI but was a good deal less expensive but don't know whatever happened to his project/kit
Good luck on which ever way you go, but if you want an LS type coil system
maybe look at a whole motor upgrade, it may cost less in the long run if you don't have the LT motor built or need to buy long tubes anyway.

even though the ltcc and the deltec doesn't elimate the opti it take away the harful voltage from the optical sensor, thus the only use of the opti a more or less just a fancy camshaft sensor.
Personally speaking i have the LTCC setup and i apsolutly love it, eventhough the install was quite detailed and time consuming.

^^ i just bought the ltcc kit... not ready to install yet since i have no motor for my car yet.... but reading through it... it doesnt look that hard to install... mostly plug and play aside from maybe 2 or 3 wires... i could be wrong but it didnt seem to bad to me...

the plug and play part and the couple wires that you have to splice in are easy, the fun part is mounting the coils and either making plug wire or finding a set to meet stock high resistance wires.

what opti are you using with your ltcc... i was going to just get a stock replacement even though the one i have seemed to be working before my tear down... im just playing it safe by getting a new one...

coil packs 
at ditching the opti on a stock/near stock car. The stock ignition system is more than sufficient for 99% of people's needs.
