I need to get a new converter for my car. When I ran Stock I always used ATI and was reasonably happy with them. After a long absence from racing I am finally coming back next year with the same car but basically nothing but the body is the same. Will now be a SS/AS car. I know a lot has changed in 12 years so I am looking for recommendations on a converter company. Will be a C4 transmission. Not saying I won't use a ATI again, just looking for options. Thanks.
