leroylucky Posted November 2, 2010 Share Posted November 2, 2010 (edited) Hey guys, Im kinda close to starting my 400hp/700R4 conversion. Ive got a 3:10 LSD r200 in the rear. What are you guys doing for traction on the street? Edited November 2, 2010 by leroylucky Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted November 3, 2010 Share Posted November 3, 2010 Add some rims and rubber and should be good to go! Quote Link to comment Share on other sites More sharing options...
leroylucky Posted November 3, 2010 Author Share Posted November 3, 2010 What would be the best size? I have 215/45-ZR17 now. Im not opposed to putting finder flares on but only if needed. Quote Link to comment Share on other sites More sharing options...
johnc Posted November 3, 2010 Share Posted November 3, 2010 Tire compound is generally more important then tread width. A 215 BFG Drag Radial will launch harder then a 335 width Sears Roadhandler. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted November 8, 2010 Share Posted November 8, 2010 3.10:1 R200? Thought 3.36:1 was lowest... Quote Link to comment Share on other sites More sharing options...
leroylucky Posted November 8, 2010 Author Share Posted November 8, 2010 (edited) When I took off the cover to see if it was actually an LSD, that's what the stamp said. I was suprised too. I have not heard anyone speak of one. I took a picture of it. When I find it I will post. Edited November 11, 2010 by leroylucky Quote Link to comment Share on other sites More sharing options...
outlaw76 Posted November 11, 2010 Share Posted November 11, 2010 I've seen 7 second rides in the 1/4 run on drag radials. Mickey Thompson has nice ones. Nitto is my least favorite, but just my opinion. E.T. streets probably be fine too. Quote Link to comment Share on other sites More sharing options...

I didn't know Sears made a 335 Roadhandler...hmmmm What size rim are you running IMO a 215 is kind of on the small side with 400 HP. I was running a 225/45/17 on a 7" rim out back I had the BFG G-force tires est HP was around 400 with a WC-T5 tranny and the 3.7 LSD. Traction= very little at full throttle.

I have not heard anyone speak of one. I took a picture of it. When I find it I will post. Are you aware that the stamp shows the teeth count on the ring and pinion and then you have to divide out to get the ratio? So a 37:11 would be a 3.36, and a 37:10 is a 3.70. Somebody just recently posted about gears from OS Giken I think, and they had a 3:15 ratio but wanted $1500 or something for them. I think for that kind of money I'd be figuring out how to put a Ford 8.8 IRS diff in. All kinds of ratios cheap and lots of limited slip/locker options too, and the housing is aluminum.

leroylucky Posted November 13, 2010 Author Share Posted November 13, 2010 (edited) Ok guys I figured it out. The stamp says 37:10. So I guess that's a 3.70. Thanks for the help. Edited November 13, 2010 by leroylucky Quote Link to comment Share on other sites More sharing options...
Pyro Posted November 19, 2010 Share Posted November 19, 2010 Need to use stock springs up front (soft) and heavy springs in the rear. When the car takes off, you want the front to lift and the back to stay still. Looks very similar to the front staying still and the back squatting, which is bad. I would use a 100lb difference in spring rate between the front and the rear. This also cures front end plow which most z's suffer from anyways. So, 230 to 250 lb spring rate in the back and stock springs up front. Then lastly, fresh rubber on the rear is important. Width has less to do with it. as long as the tires are at least 215's you should be ok. Quote Link to comment Share on other sites More sharing options...
