Hello all,

Just picked up a 1998 Formula that I will be prepping for ESP class in SCCA Autocross. It's Blurple, but I don't care too much about my cars look (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

I have some other things to take care of first, but wheels (17x9 or 10+) and suspension should come soon. I plan on Koni yellows and GC coilovers.

Ahh yes brain fart. I meant it as the torsen helical gears and auburn cone gears are not serviceable.

In terms of wear, you may only use your car for racing only maybe once a month and have had 3 diffs in 10years. I will DD mine seeing 10k mi if that per year and autocross once a month during autocross season.

Do you think DD a diff with monthy autocross needing replaced once a year?

I have an '01 Firehawk with original Torsen and 60,000 miles. It still leaves two black strips out of every corner, only serviced once, and it gets driven HARD.
The racecar with the Auburn was built and used for mini-enduro races of 1 hour or more, on my home track with most corners as tight as any AX course, but with fast entries to most corners.
I gave up on the Torsen in the first season of racing as it just did the 'one tire fire' all the time. The Auburns have stood up and worked well. The first one I folllowed the instructions and added the lubricity additive they send in the box. Bad idea for a race car, its quiet, but it slips too much. I filled it without synthetic or additive (Red Line HD) and got all the bite I needed.

Only caution is that Auburn will ask you to prove (send pic) that you will use their Racer's Diff. in your race car. I assume that means it will not last as long in a DD due to the higher bias.

I know this is a very subjective question, being that they are such dissimilar diffs, but does the Auburn Racer's diff seem to be at least the equal, as far as bias goes, to the T2R, or not??

This question is open to others who may have had BOTH, if you have never used a T2R.
