Without driver.
1600 rear wheel drive starting weight + 200 times displacement in cc + 1400 cc for forced induction
1600 + 200(1.839+1.4) =2247.8

You should weigh your car, I bet you are close to that if not over. I did quite a bit of work to get there.

 

I bet you're close to 2k lbs. My ITA Miata weight 2080lbs without trying to remove anything crazy. And that was with a full cage and hardtop (no softtop).

 

I love how off topic this thread went

Good stuff though

 

Who started this thread anyway? They should have known we wanted to talk about holes and weights ....

Back on topic.

What spring rates are you going to? There did seem to be quite a bit of body roll. On track it won't be as pronounced as the autocross since the transitions are usually smoother.
Also, what was the rattling? Sounded almost like you had something loose in the trunk.

 

Ooops, didn't see this post.

I'm on a Koni Cupkit suspension off an NB. So NB tophats, and springs meant for an NB. Unsure of rates... soft is all I can say . I also had the shocks revalved to SPSS3 spec... so I'm all set for higher rates.

I do have a set of coilover sleeves enroute, with 12k/6k rates. Should give me a bias of about 300 higher in front vs rear.
Has an FM front bar and no rear bar.

Also, just got a fresh alignment... at the AutoX the last alignment it was on SUCKED.... -.7camber front and -1.7camber rear.

I just got done redoing it at another Firestone I like more....
F: -2.4camber, 0 toe
R: -2.1camber, 0 toe

Should be MUCH better. I'll also be going out on 225 RA1s next time... no more fooling around on tires too small for the car to get grip with.

 

Who held the event?

 

hell my 99 sport with hartop on (and a/c) and me (158) was 2533lbs

so about 2325

 

Splitime where was that at? Was it with WCMC?

 

Splitime your car looks like its got a lot of torque there.

 

It was with Windy City Miata Club as Apex guessed. It was up in grayslake, il at College of Lake County.

They have an event on the 1st... but there is another club holding one closer to me... so I'm torn. I know more people going to the local one... but they get larger turn outs so I might get less runs.

I suspect... I might head to the WCMC one at CLC on June 1st... just to run with a smaller group that has more miatas.

Chicago folks should come out... seriously. Its worth the drive upto Grayslake to get out and drive the car hard.

 

Let me drive your car.

 

Yeah.... no.
