GT4 B-spec times with different mods - F-Body Road Racing and Autocross Forums

I decided to play around with GT4 the other night and let B-spec (computer) run laps at these tracks in order to try and have some consistency (although they aren't super consistent either). I ran the car stock, and then with some mods in different stages (trying to make it like my modded car). I tried to take the 1st two lap times, but sometimes I missed the 1st one. Here goes (all items are added to what car had previously):

Laguna Seca (B-Spec pace - Fast)

Stock 2000 Camaro SS - 1:46.151, 1:47.397
404HP, Brakes, Clutch, Al Flywheel - 1:40.607, 1:40.575
Suspension - 1:40.528, 1:40.142
Soft Tires (not super soft) - 1:33.364, 1:34.073
Weight removal, cage stiffness - 1:30.949

Sears Point (B-Spec pace - Fast)

Stock 2000 Camaro SS - 1:53.176
404HP, Brakes, Clutch, Al Flywheel - 1:50.367, 1:51.719
Suspension - 1:50.181, 1:49.367
Soft Tires (not super soft) - 1:40.654, 1:39.825
Weight removal, cage stiffness - 1:37.024

Not scientific by any means, but interesting to see since GT4 supposedly has rather accurate lap times and physics models. Tires made the biggest difference. I'm curious to see their affect on the stock car without the mods. Weight removal was 585 lbs. which is probably about 100-150 lbs. more than most of us can realistically take out, but you get the point. I also didn't do the quick conversion from lb/in to kg/mm so I'm not sure how accurate the spring rates were.

Pretty much in both cases, about 16 seconds were shaved off lap times from a stock car to a modded car like mine. Some of you guys have sick HP which would be even faster! :drive:

Boy, what a car geek can do when he has too much time on his hands (IMG:http://www.frrax.com/rrforum/style_emoticons/default/biggrin.gif) ....meanwhile I have lexan to install (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif) . It's snowing here again. My 1st track date is one month from today at LRP which now has about 6" of snow. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)

Although the guy with basically my car and more experience was doing 1:43's I believe... I guess the acuracy is off. This was on the sports car course, not the stock car one. Not sure how much of a difference that makes. Wonder how the Laguna Seca times compare with real life.
