i hate it!, no car that i drive should ever push!

im on a budget so, what is the cheapest way to get rid of some of the push?

oh, stock 1988 gxl na, with nice rims and good tires.

learn to drive better?

The cheapest way I know is free: use trailing throttle oversteer to bring the back end out, and then use the throttle to keep it there.

Icemark

Tire air pressure

Another freebie is that you could disconnect your front sway bar and convert some of that understeer to roll. I wouldn't recommend that as a permanent fix, but you could try it at an autocross or something (I assume Mazda put that bar there for a good reason)

Well as a person whose experianced no front bar driving, I wouldn't reccomend it. I had just installed my RB sways and the front bar endlink came undone shortly after. The car rolled A LOT and I got terrible inside wheel spin. I've got an open diff and it's never happened to me other than that.

If you want oversteer the best part to buy would be a stiffer rear swaybar, but that could cause too much oversteer. Changing driving can help, so can changing tire pressures.

slow_2ed_gen

hell yea, try 38 front 34 rear and play around with it till you have the right set up for your mods

air pressure is everything

GodSquadMandrake

Springs and swaybars.
Relocate battery to the rear.
Weight reduction in the front in general.

The RX7 seems like it needs to be transitioned slower than say for instance most FWD cars i've driven. Try transitioning more slowly into the corner, don't snap the wheel. I've found that I can increase my overall front end grip that way. I don't know why that is, maybe it's just the weight balance.

i know how to drive, check out my videos at mckeeferyracing.com

remove the front sway bar?, um no thank you, it already rolls bad enough.

i dont want to remove weight off of a tire to make it turn better, like only adding a rear sway bar will just pick in inside tire off the ground, in general thats much slower.

the only way i can get this car free is to let of the gas abruptly to transfer weight to the front tires to make it rotate, but that doesnt last long.

i think my real problem maybe that the rear end is squatting too much and pulling weight off the front tires.
i dunno, maybe stiffer springs.
im not used to driving a car where there is no chassis, and this car flexes like crazy

Keep in mind that you said you were looking for CHEAP ways to reduce understeer!

rotorpower27

ok, yes i did. but i didnt say free though, tire pressure is free and removing the front sway bar is free..

i will play with the tire pressure, but i cant go to low, because the tire profile is really small

buttsjim

Well, I think your best bet is to just use weight transfer.

By the way, I sympathize with you. It's been many years since I autocrossed, but I used to induce such horrible understeer that I could barely hold on to the steering wheel. I learned about trailing throttle (weight transfer) quite by accident, but loved it the moment it was discovered!

Icemark

Yes, exactly.

new stabilizer bars are not cheap and may not fix the issue...

rotorpower27

well, what can i do. there has to be somthing, this seems to be a problem with the rx7

Spend money and buy a good suspension. Coilovers are always the way to go. i'm saving up for mine.

Rotarctica

FCs understeer when you force them at lower speeds. You *could* try a bit of Scandinavian Flick, and possibly add power or a quick jab of the clutch while still on the gas. That'll bring the back 'round for sure.

Valkyrie

Ovals don't count

Also, it's a 20 year-old street car. You can't possibly demand race-car performance out of it.

Rotarctica

Need I remind you, these cars were designed to hold the road....not drive around sliding like mad..

If your rear end is squatting and the car is flexing, something is seriously wrong with your RX-7...

Another important Q. How big are your tires up front?

I had some nasty oversteer from my 205's. I went to 235 es100's and I take turns so much better now.

Contact patch+tire quality+suspension have a lot to do with keep the car moving the way you want.

Rearend sqautting can be from worn rear shocks.

I run tokico's up front and stock rears and my car squats when I give it gas.

buttsjim

Check your PMs.

By the way, you can make helpful minor adjustments to the camber and caster by turning the shock mounts and stacking the tolerances/clearances in your suspension pieces.

Rotarctica

Well yeah, something wrong with your RX-7 includes worn suspension...the flex confuses me...My car is stiff as hell, and it's stock. I've had cars that flex before :-X

I have no problems at all with understeer, but I have coilovers. I think that new suspention (at least oem replacement struts and springs if on a major budget) would help a good bit. Just remember that the FC is a GRIP car originally. You can get the car to do what you want, but it may not be super cheap.
For example, I recently went to the Zoom Zoom live thingy. I drove an Miata and an RX-8 back to back on an autocross course. The Miata was very easy to get the tail out around the corners, while the RX-8 wanted to stay planted more. Its all in how the car is setup. There are people out there that do excellent with RX-8s in autocross, but they probably have aftermarket suspentions.
Edit: I also think the "flex" has to do with worn suspention. Mine has ZERO flex at all.

rotorpower27

a_drift is your avtar a pic from altamont speedway?

yes money can solve anything, but i dont have enough

for the flex, i can hear the rear hatch moving, and sqeeking a bit.

i have small tires on my car, but they came with the car...



(yeah i know it needs to be lowerd, i just wish i had the money.

Icemark

looks pretty bad with those rubber bands for tires.

so someone f@#ked up the ride and handling with tiny tires and now you want a band aid to fix the suspension???
