little backstory to this... two weeks ago when i got the car i immediately was called out by a friend of mine in his built b- series, ported head, skunk cams, intake, exhaust, naturally aspirated civic... the guy means well but he doesnt know what he doesnt know... so i obliged him at whatever mph roll he chose, and gave him half a car and the move, from 40 mph this was what happened... spun what was left of second, all of third, and backpedalling in fourth finally decided to come around him and walk away. yea it appears that i was plaing in oncoming traffic but i was in fact in a center turning lane for the majority of the shenanigans... click the thumbnail for video (chase car is a modified prelude)

i apologize in advance for the 480x480 resolution... i guess this guy shot the video on a potato

Not Too Bad Phil.
She is a pretty good runner I agree.

Can You fit a 225/70 R15 tire on the rear Phil of the RX-7 ?
27.0" - 27.5" TALL Depending upon manufacturers.
Was a popular size on Muscle Pontiacs & C3 Gen Corvettes.

havent picked up another race yet and thanks for the compliments... im still figuring out how to drive the thing.. the position of the shifter and its angle are unlike anything ive ever driven before and to say it takes a learning curve is understating it... as for tires, the wheels i have are 16's and i got some 255/50/16 mickey thompsons...

It may be time to plan and Fabricate Frame Rail connecctors Phil.
Biggest single improvement you can make to a Unibody car.
Weld them in MIG OR TIG.

See how long the RX-7 IRS Holds up.
Solid axle layout be best.

Subframe Conectors made from 1"x3" retangular tubing would work nice.
Diamond style configuration as 3rd & 4th gen F-body aftermarket frame connectors store bought.

by the way, the mickey thompsons make this car a whole nother animal... this thing HOOKS now. slayed a buddies bolt on LS3 camaro today out of the hole, first gear roll, second gear roll, third gear roll, there was no place in any part of his powerband where it looked like he might have had a glimmer of hope... he pilots that car to 12.50-12.70 at the track pretty consistently. needless to say im excited for the future. :twisted:

That even puts a grin on Bob's ugly face and mine to!!! :P

I love my MT tires, they look great and grip well, but not like yours I'm sure.
Those tires mean real business. Hard to call your tires DOT approved.

another kill, coworkers 2008 duramax 2500 with upgraded injectors, tuner, fuel pump, claimed 550hp on the dyno, raced from a dead stop i was a headlight ahead in first, shot out two or three cars in second, another couple cars in third, shot fourth and fifth to be a show off and let out in the middle of fifth... he caught up to me a mile from where we started to give me a thumbs up. im starting to get a feel for the car but it desperately needs anew shifter and a knob...
