Rallycross!

I've done a couple of Rallycrosses and one Road Rally here in Wisconsin and I was curious if anyone else has any experience with this. More specifically I'd like to talk about any modifications that would help it do better in the dirt because my 85 is still very close to stock. It really isn't bad the way it is and I have taken one first place so far in Rally Stock Rear. I'm going up against mostly BMW's so I have a little bit of a weight advantage to work with. I'm considering a Blacktop 20V Swap and maybe some beefier suspension. So far I have removed the front plastic lip to give it a little better clearance. I'm looking for a good muffler too that I can weld in place of the stock one, which will make it louder and possibly gain a little bit of power

I'm also going to take this car Ice Racing this winter and I'm considering trying a Winter Road Rally

It would be awesome to find someone in the area with an Mr2 that wanted to get involved with this as well, so let me know if your interested

I rallycrossed my old 85 for a few seasons. These are very good in stock form. The only problem I seemed to have with mine was turn in. It would understeer too much until I started getting harder on it. I ended putting a full set of Tokico Blue shocks and that made a huge difference.

Also, I actually took off both sway bars and it seemed to neutral it out quite a bit in the dirt.

But, the best modification that you can do is to get a decent set of snow tires on there. It won't bump you out of class, and it has WAY more grip on nearly any surface they will have you on. The best that I've seen so far for the money is Winterforce (I think they are made by Firestone). They have an agressive tread pattern and they also have good sidewall tread to them for digging through the dirt while you're going sideways rather than pushing and piling the dirt up along side of the tire.

I raced mine in PR for the seasons I ran mine. There was only one other person in the class (and they were using my car as well) so we were always battling.

Just remember, you don't always have to have the most powerful car out there too win. We had a guy with a 3 cylinder, 1983 Subaru Justy hatchback take an overall win against WRX's and turbo'd DSM's.

As you can see in the picture, I always put my headlights up and then moved the switch one more spot so they were turned off. Being that they are right at the front corners, it was like having flags on the front of my car to know how far away from the cones I was. Works like a charm. Also, in this same race I spun a full 360 while on course without stopping or hitting a cone. TWICE!! I determined that must be why I raced such a short car.

One other thing I forgot.

Probably one of the best things that you can do is either install 5 (or 6) point harnesses. If you don't want to do that there is another way to plant yourself in the seat better. Take your seatbelt and click it in. Then pull it all the way out until it stops. Now when you let the belt come back to your body, pull it really tight. It should lock in at that point.

Basically anything you can do to plant yourself solid in the seat will help you out. The less you have to use your arms and legs to hold you in place, the more body parts you'll have free to turn the steering wheel and use the pedals. It sounds goofy, but it works. There has been a long running argument about allowing seatbelt harnesses in stock class. The that want them in there argue that they are for safety, while others argue that it can be a "performance enhancer" for the driver. I will agree with both of them. I noticed much easier control of the vehicle when I was strapped into my 5-point harnesses rather than just my seat belt. And I was still using the stock seats!

Hey, small world. I'm near Milwaukee and have plans of making my shell into a cheap as close to stock to keep prices down rally car out of my 85. Would love to know where to rallycross and/or practice in Wisconsin. So far, I only know about gravity park and the ice racing on our frozen lakes.

I've got some ideas that we are going to be doing to my mki to make it more rally friendly.

Nice! Let me know if you need any parts because I have some extras lying around... Do you have an engine for your shell? I have an extra 4age that could be assembled

Yeah I did a couple events at Gravity Park this year. It seems they might be doing something different next year though. Wheel to Wheel Rally Racing! Sounds exciting but the cars would have to be prepped accordingly. I'm still waiting to hear the details about it. I haven't done any of the ice racing yet but I will be trying that out for sure this winter! I heard that is the most fun. It will be on Lake Sinnissippi in Hustisford, WI. It's pretty close to Milwaukee actually. Hopefully you have your car ready for it, I'll look forward to running with another Mr2!

I just bought an '87 MR2 last weekend for Rallycross! I autocross in my '06 Scion xB (yeah, that car) & tried a RX event last month in a loaner Ford Probe we had for rent. I LOVED IT!

The RX Chair told me to get some used snow tires cheap & come have fun. I do plan to do a few things, probably gut the interior (the loaner was covered in dirt), 6 point harness, maybe a roll cage & new seat someday.

Agreed on the horsepower item mentioned above, I saw Neon's kicking WRX's butt's that weekend. Wish you were closer to Dayton OH, I'd love to run against another MR2!

I would say that this is *the* best thing to do. You'll gain all kinds of time by not having to fight to keep yourself in the seat.

Also, whatever you do engine-wise, keep the power curve linear. I've rallyxed my MR2 ('91 NA) and DSM ('95 GSX). The MR2 was much more effective due to the wonderfully wide torque band of the 5S-FE. The DSM was a royal pain (big turbo + cams + VPC result in no power at first, then BAM! all 4 wheels instantly spinning). Hard to rallyx with an on/off switch for a throttle... :-)

Hey, I have an 89 mr2 that I Rally-X in Colorado, we have a small stock 2wd class, so I always have to compete against the front wheel drive cars, but I'm getting better and beating most of them on a regular basis.
I run the firestone winterforce tires 185/60/R14 in the front @ 32-35 PSI
I runa set of Kelly Snowtracker 185/65R14 in the rear @ 34-36
Changing the rake helps keep the car from pushing under acceleration
I've also made some adjustments to the toe and camber on all four corners of the car, which have greatly helped, I'm still running a front sway-bar, but will soon test without it just to see what happens.

I put in a Magna Flow muffler, and its sounds really good a higher RPM'S!!

So far, so good. Looking for a long tube header to do a complete custom exhaust.

A local racer who some might have heard of Brianna Corn, opened up her own Rally x on her property and also helped build the one at Harris Hill raceway for sprints. Its mainly dominated by STI's RS's w/ full STI swaps, a few BMW's and some oddballs. I might try and make it out to one when my car is finished.

I'm planning to try my first rallycross events next year with a stock 88 MR2. Do I need to do any prep on the car, other than what I would normally do for an autocross? Screens over the radiator or skid plates under some key areas underneath?

Rallycross appears to just a AutoCross event in dirt. The cones, the short course setups and the controlled entry and exits. Yep, dirty autocross. Then again, I'm a big follower of the pro Rallycross events on the TV for the last few years. Wide open tracks, many bumper to bumper cars etc.
The idea of the passenger who appears to do no navigating is definitely peer oriented. However if your going to the event depends on the Mrs sitting next to you, ah whatta going to do but ask her to shut up during the race.

1. As a experienced driver my advice for you is to get your damn right hand off that shift lever dude. Don't keep that hand OFF the lever, that's street crap. Bad habit.
2. The other comment on your driving style is to not cross your arms when making full corners. Look at your video, where you see your arms in a X atop the steering wheel your not doing it right.

My advice for our car in this type of racing is to go to a taller height coil spring (at all 4 corners) and a longer strut cartridge to match. A semi-metallic pad or a organic may also give better performance in those cold temps.

Have fun and clean your boots before using the pedals.
