I applaud your efforts. A lot of people talk badly about these cars being FWD. You just have to set up a front drive car differently than rear drive. I have found a stiffer rear sway bar helps a lot. Mine is built for street, not track. A different set up, but the basics are the same. You can do a lot with FWD. ...J.D.

I found the stiffer rear sway bar helps keep my inner front wheel from spinning as much. If I had the money I would also go to a limited a limited slip diff. I still have some issues in the rear. Rough surfaces make the rear wheel "pogo stick" sometimes (my wheels are much lighter than the stock ones). I suspect I need to work on the rebound adjustment on my rear shocks. As mentioned, mine is for street use only so I cannot go to more extreme measures and still let my wife use it now and then. Just an old retired guy playing around. ...J.D.

What I experience with the rear of my car is not like bump steer. It is just an out of control isolation on the side rolling over a rough surface. I need to dampen the spring a little better, but only in the rear. I know what you mean about the car getting a " little floaty" at speed. I have even experienced that on the street in a few of my crazy moments. These cars try to fly above about 95-100 mph. The factory wing is just for looks. The trouble is most wings made for these cars are more for looks than they are useful. What is needed is something that is NOT TOO big but has either an adjustable angle of attack or a replaceable wickerbill. Pretty much needs to be hand fabricated. ...J.D.

You'll have to decide just how much wing you want. The more surface, the more drag. Mine has no problems with the front lifting, just the rear. I toyed with the idea of fabricating some risers to remount the stock low wing to raise it up and give it some angle of attack but I'm not going to change it. I have no business going that fast on the street. ...J.D.

I have the long cold air intake for mine, but they will not pass smog in California with it on. It is stored away right now. I am waiting for winter to hopefully get some work done on the cars and bikes. I own two houses so that seems to be all that gets worked on until the weather turns cold. ...J.D.

Does your car keep up in this field ? What other vehicles are you racing with in your class ? I notice you are running Falkin's. I tried several brands on mine. Falkin, Khumo's. I am now running Dunlop DZ-102's. So far they seem to have the most grip. Tire life is a bit short though. ...J.D.

Of course mine are a street tire. But I was amazed at the difference the tire compound made. Another big change was when I went up 1" in wheel width and kept the same tire size ( 225-45X17). It spread the tire a bit and flattened out the tread. Made a huge difference. My tire diameter is almost the same as the stock 215-50X17's and only 10mm difference in section width, but the grip is awesome ! I want to stay with the 17's so as not to effect the drive ratio. I see about 1mph faster speedo reading at 90 mph. ...J.D.

I am an older guy. Lost the desire to make a lot of noise. I leave that to all the tuner kids in the neighborhood. I WOULD like to run a few SCCA Solo events though. Don't think I am up to any wheel to wheel action. Just an old guy that is still young at heart. Hard to find time these days. My life has too many different things going on. ...J.D.

While we are speaking I need to correct you on your tire size ...You say you went up 1" in tire size and see 1mph at 90 .. Really ..the opposite is true.... look at this chart .. With old age I guess your mind is playing tricks on you .... Let`s call it a brain fart ... Tire Size Comparison

No. I went up 1" in rim WIDTH to 8.5". Tire diameter actually down, but only slightly. That was due to going from the original 215-50 to a 225-45. The lower aspect ratio coupled with speading the tire out a bit made the tire shorter. [tire is shorter so speedo reads faster. No brain fart on this end]. Probabily less then an inch though. Still using 17" wheels. ...J.D.

No problem. True, we all struggle with keeping the brain cells active. almost 13 yrs. retired. I have to have six things going at one to keep my attention. I miss a few things at times but I am fighting it for all I am worth. Beats the brain rot of sitting watching sports. Been some sort of a tech all my life. Have to keep the brain cells going. The body is falling apart.

Chinchooter11: I notice in engine compartment picture you have the factory tower brace. Did that come on the car, or did you add it ? I was under the impression they only came on the convertible. ...J.D.

Does looks really matter ? I agree it could use a better wing. I have that same one. It is a do nothing piece of plastic. I do not have much complaint with the front aerodynamics. But the rear tries to fly if you push it too fast. Need to get all the aerodynamics sorted before you take it to the painter. ...J.D.

The less aerodynamics you have to add the better. More wing, more drag. Your coupe is probably a little better that way than my Spyder. I would like to find a effective wing that will bolt right in to the original mounting holes in my decklid, but I don't think anyone is making them. ...J.D.

In all honesty, I have no reason other than aesthetics to change the wing on my 3g. It would really have no effect below about 90-95 mph. Mine is a street only car. Yes, I have had it WAY faster than that a few times, but I have to resist that urge with all my might

Not getting much done on my car or my bikes yet this year. We had a early cold spell so I had to go up and winterize my cabin this week. Drained the water system and installed a low temperature thermostat to keep things from freezing. No more than got home and I got a message from the power company that the power went out up there due to high winds. Guess I'll get to do some shop time as soon as the winter settles in. Sounds like you are having more fun than I am right riow. Enjoy ...J.D.

Still the misfire issue ? Could be so many things. Weak coil ? Injector issues ? Low fuel pressure ? Hope you get it sorted soon. Kind of spoils the fun. Have a good season. Be safe. ...J.D.

Thanks for the video. I like to see people making a racing effort with one of these cars. My only question is a minor one: Is the location of the electric cutoff behind the license plate allowed by tech inspection ? I would think they would insist it be in plain sight and labeled. ...J.D.
